Question

A transistor is operated in common emitter configuration  at constant collector voltage  Vc $$=$$ $$1.5$$ V such that a  change in the base  current from $$100$$ µA to $$150$$ µA produces a change in the collector current from $$5$$ mA to $$10$$ mA. The currentgain $$($$β$$)is$$

AC current gain βis defined as the ratio of the change in collector to the change in base current at constant  collector voltage,β$$=$$∆iC∆iBVc Given ∆$$iC=10$$ $$mA-5$$ $$mA=5$$ mA ∆iB $$=$$ $$150$$ μA $$-$$ $$100$$ μA $$=$$ $$50$$ μA ∴β$$=5$$ $$mA50$$×$$10-3$$ $$mA=100$$

A transistor is operated in common emitter configuration at constant collector voltage $V_{c}$ = 1.5 V such that a change in the base current from 100 µA to 150 µA produces a change in the collector current from 5 mA to 10 mA. The currentgain ( $β$ )is
