Question

In Fig . `V_(0)` is the potential barrier across a p-n junction, when no battery is connected across the junction

A. 1 and 3 both correspond to forward bias of junction
B. 3 corresponds to forward bias of junction and 1 corresponds to reverse bias of junction
C. 1 corresponds to forward bias and 3 corresponds to reverse bias of junction.
D. 3 and 1 both correspond to reverse bias of junction.

Answer 1

Correct Answer - B
Height of potential barrier decreases when p-n junction is forward biased and it increases when junction is reverse biased.
