Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
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 form 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.
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 form 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.
View answer and explanation
Correct option: B
A is correct but R is not correct
Option B is correct because Assertion A is correct: diffusion current is greater than drift current in forward bias. However, Reason R is incorrect: diffusion current is from p-side to n-side in forward bias.
