Question

The emitter of a transistor is generally doped the heaviest because it

Answer 1

Answer:

The role of the emitter region is to emit or inject current carriers into the base region, which then moves to the collector region of the transistor, where the transistor outputs the current signal.In a bipolar junction transistor, majority charge carriers flow from the emitter to the collector and then out from the collector. In other words, when electrons flow from emitter to collector, the current flows from collector to emitter for NPN transistor and vice versa in PNP transistor.The reason the emitter is the most heavily doped region is because it serves to inject a large amount of charge carriers into the base, which then travels into the collector, so that switching or amplification can occur.
