NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Easy-Class 12
Consider a diagram of a p-n junction diode with a forward bias applied. Which part of the diagram illustrates the reduction in the barrier height due to this forward bias?
A
The reduction in the width of the depletion layer.
B
The increase in the energy levels of holes.
C
The decrease in the built-in potential V0.
D
The increase in the electron concentration on the n-side.
Correct Answer
Option A
Detailed Explanation
In forward bias, the depletion layer width decreases and the barrier height is reduced, leading to more carriers having the energy to cross the junction, as per the context provided.
