NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Hard-Class 12
Consider a diagram showing a p-n junction with a depletion region at equilibrium. Which of the following best describes the process occurring when the junction is forward biased?
A
The width of the depletion region decreases.
B
The width of the depletion region remains unchanged.
C
The potential barrier increases.
D
Electrons move from the p-side to the n-side.
Correct Answer
Option A
Detailed Explanation
In forward bias, the external voltage decreases the barrier potential, reducing the width of the depletion region as more carriers are able to cross the junction.
