Question

In the figure shown $V_0$ is the potential barrier across a p-n junction, when no battery is connected across the junction. Which of the following statement is true?

• 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

Answer 1

Answer: (C)

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

The graph $\text{1}$ represents the forward bias because it is more than the potential barrier $V_0$. And the graph $\text{3}$ represents the reverse bias because it is less than the potential barrier $V_0$.
