Answer:

The voltage divider biasing is used biasing CB amplifier. Emitter base junction is forward biased by voltage across R, and the collector base junction is reverse biased by the voltage across Rr Coupling capacitors block DC and allow AC to pass through. By pass capacitor CB by passes AC.

During positive half cycle of input signal, forward bias on the base emitter junction decreases as it is reverse biased,Hence Ic and ICRC is decreased.The output voltage VCB is increased because VCB = Vcc – ICRC. Thus positive half cycle is obtained at the output.

During negative half cycle of the input signal, forward bias on base emitter junction is increased. Hence IE, and Ic increase and IC,RC also increases. As VCB = Vcc – IcRr, VCB decreases as LRr increases. Thus negative half cycle of output is obtained. The input and output signals are in phase.

2nd PUC Electronics Question Bank Chapter 3 Transistor Amplifiers 8

During the positive half cycle of input signal, forward bias emitter base junction increases. Hence base current IB, IE and Ic increase. This makes ICRC increase. Output voltage VCP is given by VCE = Vcc – ICRC. As ICRC increases, VCE decreases and negative half cycle at the output is obtained.

During the negative half cycle of ac input signal, forward bias on emitter base junction
decreases. Hence IB, Ic and IE decrease, decreasing ICRC.

The output voltage VCE = Vcc – ICRC. As ICRC decreases, VCE increases and we get positive half cycle at the output. Thus there is a phase difference of 180° between the input and voltage.

Question 11.
Explain the working of a CC amplifier?
Answer:
The circuit of a single stage common collector amplifier using npn transistor is shown below:
2nd PUC Electronics Question Bank Chapter 3 Transistor Amplifiers 10

The ac is applied between base and collector terminals collector circuit. The collector of the transistor is at ac ground as Rc = 0 Vcc, R1,R2,RE provide voltage divider DC bias with constant operating point in the active region. The output is taken across the emitter resistor RE. C, and C2 are the coupling Capacitors which block DC and allow ac signal.

During positive half cycle of input signal, forward bias on emitter base junction increases. Hence the base current emitter current and IERE increases which is output voltage. Hence we get positive half cycle at the output.

During negative half cycle, forward bias between emitter base junction decreases. Hence, IB, IE and IeRe decrease which is the output voltage. Thus negative half cycle is obtained. The input and out signals are in phase. CC amplifier is also called emitter follower because emitter voltage follows the base voltage.
Vo= IERE = Vin -VBP
Vo = Vin -VBP  is very small
∴ Vo ≈Vin

2nd PUC Electronics Question Bank Chapter 3 Transistor Amplifiers 11
The direct coupled amplifier using two npn transistors is as shown in the diagram. In this method, output of first stage is directly coupled to the input of second stage.

2nd PUC Electronics Question Bank Chapter 3 Transistor Amplifiers

It is then applied to the base of transistor in the second stage. Hence it is amplified A2 times. The gain of the direct coupled amplifier is A = A x A . Direct-coupled amplifiers are used to amplify extremely low frequency signals.
2nd PUC Electronics Question Bank Chapter 3 Transistor Amplifiers 12
Frequency Response of Direct coupled transistor amplifier.

Question 13.
Explain the working of RC coupled amplifier.
Answer:
2nd PUC Electronics Question Bank Chapter 3 Transistor Amplifiers 13
RC coupling is most widely used method of coupling signal from one stage to next stage in multistage amplifiers. The two stage RC coupled amplifier is as shown in the diagram. The signal developed across the collector resistor Rc of the first stage is capacitively coupled to the input of second stage through the coupling capacitor Cc.

RC coupled transistor amplifier is widely used as it provides excellent audio fidelity over wide range of frequency.

R1R2,Rc,RE provide biasing resistors. RE provides stabilisation and CE is used for bypassing ac across Rg.

Working:

When an AC signal is applied to the input of first stage, it gets amplified and appears at its output with a phase reversal of 180°. Through the coupling capacitor Cc, the amplified signal is fed to the input of second stage.

Cc blocks DC and allows AC to pass through. The second stage further amplifies the signal, further providing a phase reversal of 180° with respect to its input. The input and output signal are in phase as the signal is reversed twice. Overall gain of RC coupled amplifier is the product of gain of individual stages.
2nd PUC Electronics Question Bank Chapter 3 Transistor Amplifiers 14
At low frequencies, reactance of coupling capacitor is high. Hence it allows only a small part of the signal to pass from one stage to next stage. Hence gain is low at low frequencies. At high frequencies, the coupling capacitor Cc offers low reactance and acts like a short. Hence loading effect of next stage increases and the gain decreases.
In mid frequency range, as frequency increases, the capacitive reactance of coupling capacitor decreases, which tries to increase gain. As capacitive reactance decreases, due to loading effect of next stage, the gain reduces. Hence, voltage gain is constant.

Question 5.
Draw the circuit diagram and explain with graph the frequency response of CE amplifier.
Answer:
At low frequencies, coupling and by pass capacitors offer large reactance. As this reactance is in series with source resistance, it attenuates the input signal. As a result, gain decreases with decrease in frequency.
2nd PUC Electronics Question Bank Chapter 3 Transistor Amplifiers 21

2nd PUC Electronics Question Bank Chapter 3 Transistor Amplifiers 22

At higher frequencies, the reactance offered by junction capacitance of the transistor and wiring capacitance becomes very low. As this is in parallel with output resistance, the gain decreases with increase in frequency.

In mid-frequency range, the resistance offered by the coupling and by pass capacitors become small and negligible. Also reactance offered by junction and wiring capacitance is quite large and negligible. Hence the gain remains a constant.

Question 7.
Draw the circuit diagram and explain the working of CE amplier. Also mention any two applications.
Answer:
2nd PUC Electronics Question Bank Chapter 3 Transistor Amplifiers 23
The power supply Vcc, resistors R1, R2, Rc and RE provide required DC bias for the transistor, C1 and C2 are blocking capacitors which allow ac and block dc. The bypass capacitor CE bypass es ac at the emitter to ground.

During positive half cycle at the input signal, forward bias on the emitter base junction increases. Hence the currents ib and ic increase. As a result, ic R increases and V decreases because VCE = VCC -icRc

Thus we get negative half cycle at the output. During negative half cycle of input signal, forward bias on the emitter junction decreases. Hence ib, ic decrease and icRc also decreases. As VCB = VCC – icRc , VCE increases.
Thus, we get positive half cycle at the output.
Thus a phase shift of 180° exists between the input and the output.
Applications: It is used as AF amplifier, RF amplifier and signal generator.

Question 8.
Draw the circuit diagram and explain the working of a CB amplifier. Also mention any two applications.
Answer:
2nd PUC Electronics Question Bank Chapter 3 Transistor Amplifiers 24

The weak signal to be amplified is applied to emitter-base junction and output signal is taken across collector-base junction.

The DC power supply, R1, R2, RE, Rc provide the required biasing for the transistor. Capacitor C1, C2 block dc and allow ac to pass through. Capacitor CB by passes ac to the ground. During positive half cycle of input signal, the forward bias between base-emitter junction decreases, as VBE is already negative with respect to the ground.

Hence iE and ic. decrease and ic Rc also decreases.
VCB =Vcc – ic R. As ic Rc decreases, VCBincreases. Hence we get amplified positive half cycle. During negative half cycle of the input signal, forward bias is increased because VBEis negative w.r.t. the ground.

Hence iC , iE are increased and ic Rc is increased. As VCB =Vcc – ic R when ic Rc increases, output voltage VCB decreases.

Thus, the positive going input signal produces positive going output signal and negative going input signal produces negative going output signal. Hence in CB amplifier, the input and output signals are in phase.

Question 9.

Answer:
2nd PUC Electronics Question Bank Chapter 3 Transistor Amplifiers 25

The stable operating point in the active region is obtained by R1 R2, RE. The input is applied between base and emitter and the output is taken across the emitter resistance RE During the positive half cycle of the input signal, forward bias on emitter base junction increases.

Hence iB, iE increase and output voltage iERE increases. Thus, during positive half cycle of the input, we get positive half cycle at the output.                                         ‘

During the negative half cycle of the input signal, iB and iE decrease and hence output voltage iERE decreases. Thus output and the input are in phase and the voltage gain is 1 as input signal is equal to output signal.

CC amplifiers are used in

  • Power amplifiers
  • Current amplifiers
  • Impedance matching devices.

2nd PUC Electronics Question Bank Chapter 3 Transistor Amplifiers

Question 10.
Explain with the circuit diagram, the working of RC coupled CE amplifier. Also explain the frequency response.
Answer:
2nd PUC Electronics Question Bank Chapter 3 Transistor Amplifiers 26
The circuit diagram shows the two stage RC Coupled transistor amplifier using voltage divider bias in CE configuration. The connection to second stage from the first stage is done through the coupling capacitor Cc.C1 couples input signal to first stage and C2 couples the signal from first stage to the second stage.

R1,R2 provide the required biasing and RE provides the stabilization. CE bypasses ac across the resistor Rc.

When the ac input signal is applied to the input of the first stage, it gets amplified and appears at its output with a phase difference of 180° This amplified signal is fed to the input of the second stage through the coupling capacitor C2. The second stage further amplifies the signal and produces a phase reversal of 180° with respect to its input signal. The signal is inverted twice and the input and output of two stage CE amplifier are in phase.

Frequency response:
2nd PUC Electronics Question Bank Chapter 3 Transistor Amplifiers 27
At low frequencies, the coupling capacitor Cc offers high reactance Xc. Hence it allows only a small part of the signal to pass from one stage to the next stage. Thus gain is less at low frequencies.

At high frequencies, the coupling capacitor Cc offers a low reactance and acts like a switch. Hence , due to loading effect of the next stage increases and the gain decreases.

In mid-frequency range, the effect of coupling capacitor is such that it maintains a constant voltage gain. When the frequency increases, the capacitive reactance Cc decreases which tries to increases the gain. As the capacitive reactance decreases, the loading effect of next stage reduces the gain. The voltage gain remains a constant as the two factors cancel each other.

XIII. Write an essay on any one of the following : (1 × 4 = 4)

Question 37.
a) Ban on plastics
Why Plastic Should be Banned :
Answer:
Introduction :
Plastic bags, though useful in many ways have proved to be extremely hamful to the environment due to one single reason – they are non – bio degradable, which means they ‘ do not decompose easily making their disposal a huge challenge. Our soil takes almost 5000 years to decompose one plastic bag. Burning them also does not help as it releases poisonous gases into the atmosphere. Despite its extreme harmful effects, plastic bags are extensively used today because they are light weight, convenient, durable and economical.

Plastic bags are the hash one pollutants of land and ocean. Banning them would mean that we will forever be free from the extreme damages it causes on our environment. Our lands and oceans will have a lot less litter in them. The adverse health effects it causes on humans, animals and marine life is irrevocable.

Banning them will tread us on a much healthier journey. Plastic bags are manufactured using petroleum and produced in quantities of trilions per year. Such huge volumes of petroleum can instead be directed towards more important basic necessities like automobile fuel.

Banning plastic will mean that we will have to find a more organic material as an alternate. A well known alternate for plastic bags are paper bags. The commodity paper is extensively used today and hence is already under mass production, causing a huge toll in our environment by the number of trees being cut down for this sake.

Now introducing paper bags will only adverse this. In the case, introducing any other organic material as an alternate for such an extensively used product will only mean a greater depletion of the already minimized natural resources.

Conclusion:
We can either look at the cons of banning plastic bags as a problem or opportunity. On realizing the need, the problem of having less natural resources can turn into an opportunity to create more natural resources by planting more trees.

Such a way that plastics have become an inevitable component in our day to day life. Plastic bags have shops or vegetable shops. But, the actual scenario is, instead of making our lives easy, these plastic bags are the root cause of various issues like environmental pollution, illness in humans and animals, etc.

Karnataka SSLC English Model Question Paper 4 with Answers (2nd Language)

Problems of using plastic bags :
The plastic bags that we rely on for our every purchases at every store are perilous for the environment. The problem of using plastic bags is much more serious than it actually appears. Various studies report that these plastic bags are the major cause of water pollution. Additionally, these plastic bags make our fertile agricultural land highly infertile by occupying the underground and avoiding the uptake of minerals by the plants.

The increased use of plastic bags makes the disposal of them a herculean task. As plastic is not biodegradable, it takes almost 5000 years for the degradation to take place. The plastic bags can clog our waterways and is also a very harmful toxin for the aquatic life. Plastic bag wastes cannot be even disposed of through incineration as the process releases harmful gases that can deteriorate the atmosphere.

On a large scale, plastic bags should be banned as they can be dreadful to wild and marine life as well. Many times, these bags are mistaken for eatables by birds and animals. The plastic, which is consumed sometimes, this could even lead to the death of these animals by suffocation.

Above all, there are some external costs linked to these plastic bags. In addition to the costs linked to the production and buying of these plastic bags, there are other costs, such as :

  • Environmental costs
  • Resource extraction
  • Resource depletion
  • Loss of quality of life
  • Economic loss.
  • Wildlife loss

Conclusion: Plastic bags are banned in most of the countries globally. However, we must understand that mere ban can never help to sort the hazardous effects of the plastic bags. It is f high time that we realize the importance of our precious environment and avoid things that can degrade our environment. So, let’s go green and healthier life

Karnataka SSLC English Model Question Paper 4 with Answers (2nd Language)

Use of Internet for the Teachers : Internet serves as a place for knowledge sharing for the teachers. Teachers around the world can interact with each other and exchange ideas via internet. This is a great way to learn and evolve the methods of teaching.

Online teaching has also given way to numerous job opportunities for these professionals. Many teachers give up on their profession after their marriage owing to the added responsibilities while many others do not take up teaching owing to lack of opportunity in their vicinity.

Online coaching has proved to be’a boon for such teachers. It allows them to deliver video lectures from their own place. This has only been made possible with the help of internet.

Use of Internet for the Management: The management of different educational institutes around the world can interact by way of internet.

They can prepare for these exams from the comfort from their home rather than relocating to a different place or giving up on their dreams.

Conclusion
Internet offers several uses but its contribution to the education sector is simply impeccable. It has actually redefined this sector.

c) Environment
Answer:
Environment means all the natural surroundings such as land, air, water, plants, animals, waste, sunlight, forests hnd many other elements. An healthy environment maintains the nature’s balance as well as helps in growing, nourishing and developing every living and non living things on earth.

In modem times the man made technological advancement has made it possible to exploit natural resources to the maximum limit. This unbridled exploitation has gravely endangered the natural equilibrium of the environment. In fact life on earth is endangered to such an extent that the future of our planet, the only habitable planet in the universe, is endangered. The existence of life on earth in future is questionable.

Environmental degradation means disturbing the natural equilibrium of nature including atmosphere hydrosphere and lithosphere. Besides the natural environment; a man made environment exists which deals with technology, work environment, aesthetics, ‘transportation, housing, utilities, entics etc.

This man made environment has adversly affected the natural environment to a very great extent. Therefore there is a drastic and urgent need to save our natural environment. This can be only done by not challenging our natural resources but to use them judiciously and sensibily, we have to conserve our natural resources, that our future generations can also have access to them.

We should stop wasteful use of natural resources, stop polluting our environment, so that we and our future generation can live a peaceful and healthy life on earth. The Government, media, educational institutions should play an enormous role in generating environmental awareness among children, youth and people in general students should be familiarised about environmental issues and encouraged to cultivate, investigative and think. They should be encouraged to acquire problem solving skills in various environmental problems.

XIII. Write an essay on any one of the following : (1 × 4 = 4)

Question 37.
a) Measures for road safety
Everyday many people are involved in road accidents. Some are killed. Many more are injured or maimed. So it is important for us to learn to use the roads properly and safely. As the roads are very busy nowadays, we should be very careful when crossing one. It is safer to use a pedestrian crossing or an overhead bridge wherever one is available.

Never cross a1 road by dashing across it. That is inviting trouble. If there are no crossings, then we must look carefully right and left and cross only when it is safe to do so. It is important that we do not try to get on or off a bus while it is still moving. Using a bicycle can be dangerous too.

We must pay attention on the road and never cycle too far out to the middle of the road. We must obey all traffic rules. Also we must make sure our bicycles are in good condition with working brakes, lights etc. These are something we can do to avoid accidents. The important thing is to stay alert at all times while using the roads.

We must know what is happening around us. In that way we can take necessary action to avoid danger whenever we see one. Road safety is very much up to how we use the roads. Use them carefully and we may be able to use them for a long time,

b. My Hobby
Answer:
My hobby is reading. This hobby got started when I was a little boy. I had always wanted my parents to read fairy tales and other stories to me. Now 1 read just about anything that is available. I read story books, magazines, newspapers and any kind of material that I find interesting.

Books provide the reader with so much information and facts. For example, I do not have to catch a disease to know that it can kill me. I know the danger so I can avoid it. Also I do not have to go deep into the jungle to learn about the tiger. I can read all about it in a hook.

Reading enables me to learn about so many things that I would otherwise not know. I learned about how people lived in bygone days of magic and mystery. I learned about the wonders of the world, space travel, human achievements, gigantic whales, tiny viruses and other fascinating things of our world. It is indeed a good hobby.

Imagine that you are Punith / Parineetha studying in Government High School, Udupi.
Write a letter to the local Electricity Board to reduce the power – cuts during evening stating reasons.
Answer:

Date: 21-11-2019

Punith,
Govt. High school,
Udupi.
The Chief Engineer,
Urban sub – division,
MESCOM, ‘
Udupi.

Respected Sir,
Sub: Request to reduce the power-cuts during evening times.
This is to bring to your attention the problems faced by the residents of Vidyaratna Nagar. For the past two months we have been facing power – cuts of long duration both in the mornings and evenings. We take strong objection to the power cuts in the evenings. While it is understandable that the production of electricity is insufficient, and has led to unavoidable power cuts, it is not acceptable that there is no uniformity in the power cuts in different areas.

It is also objectionable that factories which consume much more electricity than residences have not been affected. The school going children have faced terrible problems with power – cuts. There is the question of safety too as the whole area is dark to power – cuts. Unfortunately, the rich can manage with inverters and generators. It is the poor who suffer.

We have lodged complaints twice before. But no action has been taken. We request you to act upon our complaint immediately and ensure that the power – cuts in the evenings are stopped.
Thanking You.

Yours faithfully,
Punith.

Answer:
He stood at the crest of the tallest hill. He was old and had wrinkled face. He had no interest in life. His head was turned downward, he closed his eyes. He wore an old faded blue shirt. That shirt was dark with sweat, the tie was tom. The jacket was old and it could not hold his sagging (hanging) stomach. He wore the old shoes which had papers inside. His face was not shaved. One could see the pain in each wrinkle of his face. He alone stood with his head down and eyes closed. He wore an old alto saxophone and chanting some religious music in low voice. That old saxophone was hanging from his neck by a wire coat hanger.

XIII. Write an essay on any one of the following : (1 × 4 = 4)

Question 37.
a. Ksheer Bhagya Yojana at School:
Answer:
This yojana includes providing milk to the children of Govt schools. As like mid day meal, this is an essential thing as majority of the children of GOVt school are coming from so poor families “that they cannot afford milk. Considering the nutritional value of milk, this is again a good gesture that keeps the physical, mental and emotional aspect of a child in check.

Whichever be the plan, executing is equally important and it should be ensured that a perishable item like milk will be served without any chance of contamination. In Govt. Schools in Kerala, it is successfully applied. The teachers provide milk and egg on certain days to the children in the morning itself apart from mid day meal. If successfully implemented, the Govt can check the drop outs in Govt school and a healthy student generation also will be a reality.

b) Role of an ideal Citizen.
Answer:
An ideal citizen is the one who is aware of his duties even as he exercises his rights. The constitution of India has assured us both rights and duties. But unfortunately, most of us enjoy our rights without fulfilling our duties. So, we can say that ideal citizen is the one who prioritises his duties over his rights.

What are the duties to be upheld by an ideal citizen? First and foremost, an ideal citizen is the one who loves his country and who is proud of his country’. So he should promote secularism and bring people of different communities together in the true spirit of brotherhood.

The word ‘brother hood’ points out that in society all of us should get equal opportunities. So an ideal citizen would strive to ensure that there is social justice and people get equal benefit without a huge gap between the rich and the poor. An ideal citizen should exhibit the virtue of philanthropy and social consciousness.

In addition to these lofty ideals, an ideal citizen should also keep in mind practical values like saving the environment, preserving natural resources, keeping the surroundings clean and protecting public amenities.

If each one of us does what is expected of an idal citizen, this world certainly be a better place to live in and we can experience the heaven on the earth.

(c) Indian farmer today.
Answer:
Indian farmers today are at the cross roads. Techology has taken huge, strides reformulating the role of farmers. If farmers do not make use of techology, they would be left behind in this fast – moving world, That is why, it is of paramount importance that Indian farmers , educate themselves and know how to succeed in the new world order of consumerism.
If they are educated, they can progress in the field of agriculture and contribute richly towards the economy of the nation. Even to this day. despite the progress it has made in the IT Sector India is recognised as an agricultural economy. Hence it is of paramount importance that India values its farmers.

But unfortunately we have seen that Indian farmers are native and hence are taken for a ride by the mediators. That is why there are many tragic cases of farmers committing suicide after being cheated by mediators who swallow a lion’s share of farmers profit margin or landlords who offer loans on high rates of interest. It is thé duty of the government to offer attractive schemes of farmers so that the nation makes progress in the field of agriculture. It is also necessary 1at the government educates farmers and also gives manure and farming equipment t subsidised rates. The would meat a bright future for India.

Respected sir,

Sub : Seeking assistance to keep the school surroundings dean.
I ‘am the student of government High school, Udupi. I am representing all the students of my school while writing this letter to you. We have a persisting problem regarding the unclean surroundings of our school. Though our teachers have encouraged us to clean our school surroundings once a week, our efforts are in vain as the households dump their garbage beside our school compound and the panchayat does not regularly lift the garbage. After a few days unpleasant smell starts emanating from the garabge mounds, have become a breeding ground for mosquitoes and their menance, dogs which come to scavenge on the garbage chase us menancingly and many students have been bitten by them. After the school hours, some anti – social persons carry out dubious activities inside the school premises. Liquor bottles, condoms, cigarette butts will be strewn about in the school premises. I earnestly plead with you to inspect and take action to stop these activities’ So that we can study in a more healthy and peaceful place.

Thanking you.

Yours faithfully,
Rakesh (class x)
Govt high school, Udupi.

Theorem: The tangent at any point of a circle is perpendicular to the radius through the point of contact.
Karnataka SSLC Maths Model Question Paper 1 S31
Proof: We are given a circle with centre O a tangent XY to the circle at a point R We need to prove that OP is perpendicular to XY.
Take a point Q on XY other the P and join OQ see in below fig.
The point Q must lie outside the circle. (Why? Note that if Q lies inside the circle XY will become a secant and not a tangent to the circle). Therefore OQ is longer than the radius OP of the circle. That is,
OQ > OR
Since this happens for every point on the line XY except the point R OP is the shortest of all the distances of the point O to the points of XY. So OP is perpendicular to XY. (as shown in theorem).
OR
Theorem: The lengths of tangents drawn from an external point to a circle are equal.
Karnataka SSLC Maths Model Question Paper 1 S31.1
Proof: We are given a circle with centre O, a point P lying outside the circle and two tangents PQ, PR on the circle from P (see in fig.). We are required to prove that PQ = PR,
For this, we join OR OQ and OR. Then ∠OQP and ∠ORP are right angles because these are angles between the radii and tangents, and according to the theorem, they are right angles.
Now in right triangles OQP and ORP
OQ = OR (Radii of the same circle)
OP = OP (Common)
Therefore, ΔOQP = ΔORP (RHS)
This gives PQ = PR
