In Fig. 14.1, Vo 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.
Answers (1)
Answer: The answer is the option (b)
The height of a potential barrier increases when p-n junction is biased forward, and it opposes the potential barrier junction. But if p-n is reversed biased, the potential barrier junction is supported, which results in an increase in the potential barrier.
