Vedclass · Accepted Answer

The emitter injects holes into the base of the $p-n-p$ transistor and electrons into the base region of $n-p-n$ transistor.

Vedclass · Answer

(C) In a transistor,the emitter-base junction is always forward-biased to allow charge carriers to move into the base.In an $n-p-n$ transistor,the emitter is $n$-type,so it injects electrons (majority carriers) into the base.In a $p-n-p$ transistor,the emitter is $p$-type,so it injects holes (majority carriers) into the base.Therefore,the primary difference in operation is the type of charge carrier injected by the emitter into the base region: $p-n-p$ injects holes,while $n-p-n$ injects electrons.

Which one of the operations of $n-p-n$ transistor differs from that of $p-n-p$ transistor?
