Question

In figure, $\mathrm { V } _ { 0 }$ 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
• C. 1 corresponds to forward bias and 3 correspond to reverse bias of junction.
• D. 3 and 1 both correspond to reverse bias of junction

Answer 1

Answer: (B)

3 corresponds to forward bias of junction and 1 corresponds to reverse

Answer 2

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