Vedclass · Answer

(D) In a transistor,the three regions are the emitter,base,and collector.$1$. The $Base$ is very thin and lightly doped to allow most charge carriers to pass through to the collector.$2$. The $Collector$ is moderately doped and larger in size to dissipate heat.$3$. The $Emitter$ is heavily doped to provide a large number of charge carriers.Therefore,the order of increasing doping level is $Base < Collector < Emitter$.

$A$ transistor has $3$ impurity regions of different doping levels. In the order of increasing doping level,the regions are
