Assertion: Photodiode work in reverse bias.
Reason: Change in diode current increases with increase in intensity.
Reason: Change in diode current increases with increase in intensity.
View answer and explanation
Correct option: B
If both assertion and reason are true but reason is not the correct explanation of assertion
Option B (If both assertion and reason are true but reason is not the correct explanation of assertion) is correct because both the photodiode working in reverse bias and the increase in diode current with light intensity are true, but the latter doesn't explain the former.
