Question:

When p-n junction diode is forward biased then

Options:

the depletion region is reduced and barrier height is increased.

the depletion region is widened and barrier height is reduced.

both the depletion region and barrier height are reduced.

both the depletion region and barrier height are increased.

Correct Answer:

both the depletion region and barrier height are reduced.

Explanation:

In the forward biasing, the applied potential difference opposes the potential barrier present across p-n junction diode.
