Question

What is the main advantage of FET which makes it more useful in industrial applications?

(a) Voltage controlled operation

(b) Less cost

(c) Small size

(d) Semiconductor device

I had been asked this question by my school principal while I was bunking the class.

My question is taken from The Junction Field-Effect Transistor topic in section Field-Effect Transistors of Electronic Devices & Circuits

Answer 1

The correct answer is (c) Small size

Explanation: Because of its small size, the IC chips can be made even smaller which reduces the wear and tear. The process technology used with process technology constant a which is the ratio of Width and Length, the FET is made more advantageous.
