MCQ
In a photo$-$diode,
  • ✓
    Photocurrent is proportional to incident light intensity.
  • B
    Photocurrent is inversely proportional to incident light intensity.
  • C
    Photocurrent is independent of the incident light intensity.
  • D
    Incident light intensity is proportional to the photocurrent.
✓

Answer

Correct option: A.
Photocurrent is proportional to incident light intensity.
In a photodiode, photocurrent is directly proportional to intensiy of incident light. More the incident light intensity, more will be the current produced.
