NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): In a p-n junction at equilibrium, the diffusion current is equal to the drift current. | Reason (R): The electric field created by the space-charge region increases until it balances the diffusion of charge carriers.
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 states that at equilibrium in a p-n junction, the diffusion current equals the drift current due to the electric field opposing further carrier flow.
