Q.
Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R [2023]

Assertion A: Diffusion current in a p–n junction is greater than the drift current in magnitude if the junction is forward biased.

Reason R: Diffusion current in a p–n junction is from the n-side to the p-side if the junction is forward biased.

In the light of the above statements, choose the most appropriate answer from the options given below:

1 Both A and R are correct and R is the correct explanation of A

2 Both A and R are correct but R is NOT the correct explanation of A

3 A is correct but R is not correct

4 A is not correct but R is correct

Ans.
(3)

In forward biased condition, diffusion of majority charge carriers takes place from $p$ -side to $n$ -side which constitute the diffusion current.

Solution

1 Both A and R are correct and R is the correct explanation of A

2 Both A and R are correct but R is NOT the correct explanation of A

3 A is correct but R is not correct

4 A is not correct but R is correct

Ans.
(3)

In forward biased condition, diffusion of majority charge carriers takes place from $p$ -side to $n$ -side which constitute the diffusion current.
