Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: Photodiodes are preferably operated in reverse bias condition for light intensity measurement. Reason R: The current in the forward bias is more than the current in the reverse bias for a p-n junction diode. In the light of the above statements, choose the correct answer from the options given below:

Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: Photodiodes are preferably operated in reverse bias condition for light intensity measurement. Reason R: The current in the forward bias is more than the current in the reverse bias for a p-n junction diode. In the light of the above statements, choose the correct answer from the options given below: (A) A is true but R is false (B) Both A and R are true and R is the correct explanation of A (C) A is false but R is true (D) Both A and R are true but R is N O T the correct explanation of A

Photodiodes are operated in reverse bias as fractional change in current due to light is more easy to detect in reverse bias.

A is true but $R$ is false

Both $A$ and $R$ are true and $R$ is the correct explanation of $A$

A is false but $R$ is true

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