A JFET has ___________ power gain
A. small
B. very high
C. very small
D. none of the above
Answer: Option B
Solution (By Examveda Team)
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.

JFET is small power gain because voltage gain high and current gain low and high input impedance
