Vedclass · Answer

(A) For a transistor to operate as an amplifier,it must be in the active region. In the active region,the emitter-base junction is forward-biased,which allows charge carriers to flow from the emitter into the base. The base-collector junction is reverse-biased,which allows the collector to collect the majority of the charge carriers injected from the emitter. Therefore,the correct configuration is that the emitter-base junction is forward-biased and the base-collector junction is reverse-biased.
