Question:

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

Options:

reduces the majority carrier current to zero

lowers the potential barrier

increases the potential barrier

decreases the majority carrier current

Correct Answer:

lowers the potential barrier

Explanation:

The correct answer is Option (2) → lowers the potential barrier

Forward bias means the positive terminal of the battery is connected to the p-side and the negative terminal to the n-side.

This reduces the electric field across the depletion region, effectively lowering the potential.
