- 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
As light intensity increases, more photons strike the photodiode, generating more electron-hole pairs, which leads to an increase in photocurrent.
