NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Medium-Class 12
Consider a p-n junction diode under forward bias as illustrated in a diagram similar to Fig. 14.13(b). What happens to the depletion layer and the barrier height as the applied voltage increases?
A
The depletion layer width decreases and the barrier height is reduced.
B
The depletion layer width increases and the barrier height is increased.
C
The depletion layer width remains the same and the barrier height is reduced.
D
The depletion layer width decreases and the barrier height remains the same.
Correct Answer
Option A
Detailed Explanation
As per the NCERT context, when a p-n junction diode is forward-biased, the depletion layer width decreases and the barrier height is reduced due to the applied voltage.
