Question # 1
Why is the photodiode operated in reverse biased state?
- Ans 1: Photodiode is used for the detection of light.So it is used in reverse biased state.Reverse current increase with the intensity of incident light.When no light incidents,then reverse current will be negligible.

Question # 1
How the normal operation of transistor is achieved?
-
Ans 1: For the normal operation the base emitter junction of transistor is forward biased and collector base junction is reverse.In a common emitter amplifier ,input signal is applied between base and emitter and output signal is taken across collector and emitter,Similarly emitter base junction is forward biased and collector base junction is reverse biased.
