For detecting light intensity we use

Options

  1. Aphotodiode in reverse bias.
  2. Bphotodiode in forwarded bias.
  3. CLED in reverse bias.
  4. DLED in forward bias.

Correct answer

A. photodiode in reverse bias.

Step-by-step solution

The device which is used for detecting light intensity is Photodiode. Photodiode is a type of PN junction that generates current when exposed to light. It operates in reverse biased mode and converts light energy into electrical energy and is also known as a photodetector or a photosensor.
