| In Figure, \[{{V}_{\operatorname{o}}}\] 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.
Correct Answer: B
Solution :
Option [b] is correct. Explanation: When p-n junction is in forward bias, it compresses or decreases the depletion layer, due to which potential barrier in forward bias decreases and in reverse bias potential barrier increases.
