Question

When a p-n junction diode is subjected to reverse biasing:

(A) the barrier height decreases and the depletion region widens.

(B) the barrier height increases and the depletion region widens.

(C) the barrier height decreases and the depletion region shrinks.

(D) the barrier height increases and the depletion region shrinks.

Answer 1

Correct option is (B) the barrier height increases and the depletion region widens

When p-n junction is reverse biased, the depletion region is increased i.e., the potential barrier increased.
