Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: Photodiodes are used in forward bias usually for measuring the light intensity.
Reason R: For a p-n junction diode, at applied voltage the current in the forward bias is more than the current in the reverse bias for where is the threshold voltage and is the breakdown voltage.
In the light of the above statements, choose the correct answer from the options given below

In the light of the above statements, choose the correct answer from the options given below
View answer and explanation
Correct option: A
A is false but R is true
Option A (A is false but R is true) is correct because photodiodes are used in reverse bias, and the statement about forward and reverse bias current is correct.
