Question

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

Options

• raises the potential barrier.

• reduces the majority carrier current to zero.

• lowers the potential barrier.

• None of the above.

Answer 1

When a forward bias is applied to a p-n junction, it lowers the potential barrier.

Explanation:

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.
