AIIMS 2000 Physics Diodes MCQ Question
Type: MCQ-conceptual-Medium-Class 12
What accounts for the flow of charge carriers in forward and reverse biasing of silicon p-n diode?
A
drift in forward bias and diffusion in reverse bias
B
drift in reverse bias and diffusion in forward bias
C
drift in both reverse and forward bias
D
diffusion in both forward and reverse bias
Correct Answer
Option B
Detailed Explanation
In a p-n diode, forward bias reduces the barrier allowing carriers to drift, while reverse bias increases the barrier causing diffusion.
