Define current amplification factor in a common emitter mode of transi – InterviewSolution

InterviewSolution

1.	Define current amplification factor in a common emitter mode of transistor.
Answer» Current amplification factor `(beta_(ac))` is defined as the ratio of small change in collector current `(DeltaI_C)` to the corresponding small change in the base current `(DeltaI_B)` when the collector emitter voltage is kept constant, i.e., `beta_(ac)=[(DeltaI_C)/(DeltaI_B)], V_(CE)`is constant.
