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

Options

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

B

Explanation

When p-n junction is in forward bias, it compresses or decreases the depletion layer, due to which potentail barrier in forward bias decreases and in reverse bias potential barrier increases.
