Question

To study characteristics of a comon emitter n-p-n or p-n-p transistors and to find out the value of current and voltage given

Answer 1

Characteristics of Common Emitter NPN Transistor

Common Emitter NpN transistor has sharp and definite input and output.

Input voltages are used to apply separately to the P-portion from base   and collector.

voltage (emitter voltage) is used to leave the emitter and enter the circuit of npn transistor.

beta=B=200

Ic=Collector Current=4x10^-3

IB=Ic/B

IB=20 u ampre
