- A.The photocurrent decreases.
- B.The photocurrent remains constant.
- C.The photocurrent increases.
- D.The photocurrent fluctuates.
Model answer
What a good answer should say
- The photocurrent increases.
Explanation
Why this works
The evidence shows that as light intensity increases, more photons strike the photodiode, generating more electron-hole pairs. This leads to an increase in the photocurrent.
The implication is that photodiodes can be effectively used in light-sensing applications. Thus, we conclude that photodiodes are responsive to changes in light intensity, making them suitable for various sensing circuits.
