$A$ few charge carriers are lost in the base and only the remaining ones reach the collector.

Vedclass · Answer

(B) In a transistor,the emitter current $(I_E)$ is the sum of the base current $(I_B)$ and the collector current $(I_C)$,expressed as $I_E = I_B + I_C$.Since the base region is very thin and lightly doped,a small fraction of the charge carriers (electrons in an $NPN$ transistor or holes in a $PNP$ transistor) injected from the emitter recombine with the majority charge carriers in the base region.This recombination results in a small base current $(I_B)$.Consequently,the remaining charge carriers reach the collector,making the collector current $(I_C)$ slightly less than the emitter current $(I_E)$.

In a transistor,the collector current is always less than the emitter current because:
