A transistor is operated in common emitter configuration at `V_(c)=2 V

1.	A transistor is operated in common emitter configuration at `V_(c)=2 V` such that a change in the base current from `100 muA` to `200 muA` produces a change in the collector current from `5 mA` to `10 mA`. The current gain isA. `75`B. `100`C. `150`D. `50`
Answer» Correct Answer - D For a transistor `I_(E)=I_(B)+I_(C)` where `I_(E)`=emitter current `I_(B)`=base current `I_(C)`=collector current and current gain `beta =(DeltaI_(C))/(DeltaI_(B))` `DeltaI_(C)=5xx10^(-3)A` `DeltaI_(B)=100xx10^(-6)A` `beta=5/100xx1000=50`
