Which of the following regions of a transistors are, respectively, heavily dopped and lightly dopped? (a) Collector and emitter (b) Base and emitter (c) Emitter and base (d) Emitter and collector

Answer: (c). Emitter is heavily doped to inject a large number of carriers. Base is lightly doped and thin so most carriers pass to the collector. So the answer is (c) emitter and base.

Which of the following regions of a transistors are, respectively, heavily dopped and lightly dopped?

Show answer and solution

Answer: (c)

Emitter is heavily doped to inject a large number of carriers.
Base is lightly doped and thin so most carriers pass to the collector.
So the answer is (c) emitter and base.
