Answer & Solution
Answer: Option B
Solution:
Think of a JFET (Junction Field-Effect Transistor) like a water tap.
You use a small amount of effort (like turning the handle a little) to control a large flow of water.
*
Power Gain means how much bigger the output signal (like the water flow) is compared to the input signal (like turning the handle).
*JFETs are excellent at amplifying signals.
This means a tiny input signal can control a much larger output signal.
*Because of this amplification, JFETs have a *
very high power gain.
They can take a small input signal and turn it into a much bigger output signal.
*The other options are not correct:
*
Small or Very Small power gain would mean the JFET doesn't amplify well.
*
None of the above would mean JFETs don't have any power gain at all, which is incorrect.
