Statement-I: A junction with reverse bias can be used as a photodiode to measure light intensity.
Statement-II: In a reverse bias condition the current is small but it is more sensitive to changes in incident light intensity.
Statement-II: In a reverse bias condition the current is small but it is more sensitive to changes in incident light intensity.
View answer and explanation
Correct option: A
If both statements are correct.
Option A is correct because a reverse-biased p-n junction can be used as a photodiode to measure light intensity, and the current in reverse bias is small but highly sensitive to changes in incident light intensity.
