For detecting light intensity we use
- A photodiode in reverse bias.
- B photodiode in forwarded bias.
- C LED in reverse bias.
- D LED in forward bias.
Answer & Solution
Correct Answer
(A) photodiode in reverse bias.
Step-by-step Solution
Detailed explanation
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.
