Question

The action of JFET in its equivalent circuit can be represented as which of the following?

(a) Current controlled current source

(b) Current controlled voltage source

(c) Voltage controlled current source

(d) Voltage controlled Voltage source

I got this question in homework.

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

Answer 1

Correct option is (c) Voltage controlled current source

For explanation: In JFET equivalent circuit, the output current is controlled by the gate to source voltage and hence we can say it is a Voltage controlled current source.
