In figure, V0 is the barrier potential across a p-n junction, when no battery is connected across the junction.

Question

In figure, V0 is the barrier potential 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) 1 corresponds to reverse bias of junction and 3 corresponds to forward bias of junction. (C) 1 corresponds to forward bias and 3 corresponds to reverse bias of junction. (D) 1 and 3 both correspond to reverse bias of junction.

Tardigrade Admin · Accepted Answer

When p-n junction is forward biased, applied voltage opposes the barrier potential resulting decrease in barrier potential. When p-n junction is reverse biased, applied voltage supports the barrier potential resulting increase in barrier potential. Thus, curve 1 corresponds to reverse bias and curve 3 corresponds to forward bias.

Q. In figure, V0​ is the barrier potential across a p-n junction, when no battery is connected across the junction.

1 and 3 both correspond to forward bias of junction.

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

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

1 and 3 both correspond to reverse bias of junction.
