(a) Source to drain

(b) Drain to source

(c) Gate to source

(d) Gate to drain

The question was asked in exam.

This interesting question is from The Junction Field-Effect Transistor in chapter Field-Effect Transistors of Electronic Devices & Circuits

Answer 1

Correct option is (b) Drain to source

Easy explanation: When a voltage greater than pinch off is applied, the current starts flowing from Drain to source.
