Q. If the forward voltage in a diode is increased, the width of the depletion region
A) Increases
B) Decreases
C) Fluctuates
D) No change
Explanation
(b) On increasing the forward bias voltage, the barrier energy decreases. This results in the flow of majority charge carriers. Hence, width of depletion region decreases.
