Statement 1: Photodiodes are operated in reverse bias.
Statement 2: The current in photodiodes is proportional to light intensity.
Statement 2: The current in photodiodes is proportional to light intensity.
View answer and explanation
Correct option: B
Statement 1 is true, statement 2 is true and
statement 2 is Not the correct explanation for statement
1
statement 2 is Not the correct explanation for statement
1
Option B (Statement 1 is true, statement 2 is true and statement 2 is Not the correct explanation for statement 1) is correct because photodiodes are indeed operated in reverse bias, and their current is proportional to light intensity, but the reverse bias is not *because* of the proportionality to light intensity.
