Question

When a forward bias is applied to a p-n junction, it

• A. raises the potential barrier.
• B. reduces the majority carrier current to zero.
• C. lowers the potential barrier.
• D. None of the above.

Answer 1

The correct option is C lowers the potential barrier.

When a forward bias is applied to a p-n junction, it lowers the value of potential barrier. In the case of a forward bias, the potential barrier opposes the applied voltage. Hence, the potential barrier across the junction gets reduced.
