Vedclass · Accepted Answer

emitter-base junction is forward biased and base-collector junction is reverse biased

Vedclass · Answer

(A) For a transistor to operate in the active region,which is required for amplification,the emitter-base junction must be forward biased and the base-collector junction must be reverse biased.In the forward-biased emitter-base junction,charge carriers are injected from the emitter into the base.In the reverse-biased base-collector junction,these carriers are collected by the collector,allowing for current control and signal amplification.
