How does light intensity affect the photocurrent in a photodiode?.
- A.Photocurrent increases with light intensity
- B.Photocurrent decreases with light intensity
- C.Photocurrent remains constant regardless of light intensity
- D.Photocurrent is independent of the photodiode's characteristics
Model answer
What a good answer should say
- Photocurrent increases with light intensity
Explanation
Why this works
As light intensity increases, more photons strike the photodiode, generating a greater number of charge carriers, which results in an increased photocurrent.
