Find the DC current gain of a pnp transistor operated in the

Find the DC current gain of a pnp transistor operated in the active region, if the collector current and emitter current are 14.8 mA, and 15.0 mA respectively.

Solution

collector current,I_C=14.8mA, emitter current,I_E=15.0mA

We know that,Base current,I_B= I_E-I_C=(15-14.8)mA=.2mA

DC current gain,Beta=I_C/I_B=14.8mA/.2mA=74
