NEET Physics (general) MCQ Question
Type: MCQ-conceptual-Easy-Class 12
In a p-n junction diode, what happens at equilibrium when the diffusion current equals the drift current?
A
There is no net current across the junction.
B
The diffusion current becomes zero.
C
The drift current overpowers the diffusion current.
D
Electrons move freely across the junction.
Correct Answer
Option A
Detailed Explanation
At equilibrium in a p-n junction, the diffusion current equals the drift current, resulting in no net current across the junction as described in Chunk 2.
