Question

HOW CAN WE USE PHOTODIODES FOR OPTICAL SIGNALS??​

Answer 1

Answer:

A photodiode may be used to detect optical signals as we observe the change in current with change in light intensity when a reverse bias voltage is applied. Under a reverse biased condition, it has a very high resistance, but when light falls on it, the resistance becomes negligible.
