17
A JFET has ___________ power gain
Discuss
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.
