NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): In a p-n junction at equilibrium, the diffusion current equals the drift current. | Reason (R): The potential difference across the junction opposes further flow of carriers, maintaining equilibrium.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true, but R is false.
D
A is false.
Correct Answer
Option A
Detailed Explanation
The NCERT context explains that in a p-n junction at equilibrium, the diffusion current equals the drift current due to the potential difference across the junction opposing further carrier flow.
