NEET Physics (general) MCQ Question
Type: MCQ-conceptual-Hard-Class 12
Which of the following statements about semiconductor behavior at the p-n junction is correct?
A
At equilibrium, the diffusion current equals the drift current in a p-n junction.
B
In a p-n junction, holes are the majority carriers in the n-region.
C
The loss of electrons from the p-region leads to an increase in diffusion current.
D
A p-n junction allows significant current flow under all conditions.
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, at equilibrium in a p-n junction, the diffusion current equals the drift current, resulting in no net current. This is a key feature of the p-n junction behavior.
