NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): In an unbiased p-n junction, holes diffuse from the p-region to the n-region. | Reason (R): The hole concentration in the p-region is more compared to the n-region.
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
In an unbiased p-n junction, holes move from a region of higher concentration (p-region) to lower concentration (n-region), and this diffusion is driven by the concentration gradient.
