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 junction diode.
In the light of the above statements, choose the correct answer from the options given below:
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 junction diode.
In the light of the above statements, choose the correct answer from the options given below:
View answer and explanation
Correct option: D
Both A and R are true but R is NOT the correct explanation of A
Option D (Both A and R are true but R is NOT the correct explanation of A) is correct because both the assertion and the reason are true, but the reason does not explain why photodiodes are operated in reverse bias.
