Hi ,
I get stuck with few questions with multiple choices.

Please suggest which are the correct answers and if possible please add some explanations.

Please see attached PDF file

Thanks.

The answer to Q1 is:

E) The one with the largest wheelbarrow.

It doesn't specify what is being carried, but perhaps we can presume it's "current". With appropriate (or inappropriate) component choices, there are at least 2 options.

Q2 - there are at least 2 components shown, but let's assume they're not talking about the capacitor. 2 of the choices should be very easy to eliminate.

Q3 - 2 options should be easily eliminated, and a third with a little thought. All that's left is what Sherlock Holmes would pick.

Q4 - 2 options can be dismissed immediately as nonsense. One of the remainder is true in a typical circuit, the other would be true given appropriate (or inappropriate) component choices. Actually I think one is true for class A and AB, and the other is true for class B and C -- although this refers to the biasing more than the typical uses for this circuit.

I suggestion..

I hope someone can share with what I think , correct if I am wrong ..

Q1: never provide any value for all components .and the question try to test the
understanding of transistor circuit role -amplication ( gain or voltage )
To me , the "output" should has bigger "current" (asuming carries refer to current),
and the answer is RL ( output ) ??

Q2: To me , this is regulation transformer circuit

Q3: Q1 and Q3 are same circuit , try to test Transistor characteritic - amplication.
The answer should be (C) DC voltage will be larger instead of (D) DC current will
be larger

Q4: I have to construct the similar circuit to test ... anyone has tried out ?

Q1: What component(s) does the current passing through RL also pass? Do these components carry more or less current than RL?

Q3: How can C be true?

Q4: It's a very common circuit. If you haven't seen it before, then I suggest you go back and read your notes or the suggested reading.
