Applying forward bias to p-n junction, the potential barrier (a) increases. (b) decreases. (c) remains unchanged. (d) becomes zero.

Answer: (b). The applied forward voltage opposes the built-in barrier. Effective barrier becomes VB - V, smaller than before. So the answer is (b) decreases.

P-N Junction Diode

Applying forward bias to p-n junction, the potential barrier

Show answer and solution

Answer: (b)

The applied forward voltage opposes the built-in barrier.
Effective barrier becomes $V_B - V$ , smaller than before.
So the answer is (b) decreases.
