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 statement, choose the correct answer from the options given below :

Select the correct option:

A is false but R is true

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

A is true but R is false

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

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

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