Q. 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:

Solution:

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