NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): In a p-n junction at equilibrium, there is no net current flow across the junction. | Reason (R): The diffusion current and drift current in a p-n junction balance each other at 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 but R is true.
Correct Answer
Option A
Detailed Explanation
In a p-n junction at equilibrium, the diffusion current equals the drift current, resulting in no net current. This balance is due to the opposing potential that prevents further flow of carriers.
