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.
