Question

# In Fig. is the potential barrier across a p-n junction, when no battery is connected across the junction:

- 1 and 3 both correspond to forward bias of junction
- 3 corresponds to forward bias of junction and 1 corresponds to reverse bias of junction
- 1 corresponds to forward bias and 3 corresponds to reverse bias of junction
- 3 and 1 both correspond to reverse bias and 3 corresponds to reverse bias of junction

## The correct answer is: 3 corresponds to forward bias of junction and 1 corresponds to reverse bias of junction
