Q174 / 180 · COMEDK 2017 · Physics

If the forward voltage in a diode is increased, then the width of the depletion region

A
increases
Correct answer
B
decreases
C
fluctuates
D
no change

Solution

When forward voltage in a diode is increased, then it opposes the potential barrier. Due to it, the potential barrier is considerably reduced and hence depletion region decreases.

Hence, the correct answer is option: 'B'.
