Given below are two statements : one is labeled as Assertion A and the other is labeled 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
and 
are true and 
is correct explanation A
and 
are true but 
is NOT the correct explanation 
is true
is true but 
is false
Text Solution
Verified by ExpertsC
Photodiodes are used in reverse bias condition. For 
- 
junction diode current in forward bias ( for 
) is always greater than current in reverse bias (for 
). Hence Assertion if false but Reason is true.
