Question

FET is a voltage controlled device.

(a) True

(b) False

The question was asked by my school teacher while I was bunking the class.

I would like to ask this question from The Junction Field-Effect Transistor in section Field-Effect Transistors of Electronic Devices & Circuits

Answer 1

Right answer is (a) True

Explanation: Field Effect Transistors are voltage controlled devices, by applying some voltage between the gate and source, the drain current can be controlled. In order to control the operation of FET the gate to drain voltage is varied to operate the FET in different regions of operation.
