AIPMT PRELIMS 2005 Physics p-n Junctions MCQ Question
Type: MCQ-conceptual-Easy-Class 12
Application of a forward bias to a p-n junction:
A
increases the number of donors on the n-side
B
increases the electric field in the depletion zone
C
increases the potential difference across the depletion zone
D
decreases the potential difference across the depletion zone
Correct Answer
Option A
Detailed Explanation
Forward biasing a p-n junction reduces the potential barrier, allowing current to flow more easily by decreasing the potential difference across the depletion zone.
