Question

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

विकल्प

• Collector and emitter

• Base and emitter

• Emitter and base

• Emitter and collector

Answer 1

Emitter and base

Explanation:

The emitter region of a transistor is heavily doped because it injects charge carriers into the base and collector regions.

Because charge carrier recombination occurs in the collector area, it is moderately doped.

Because the base area is weakly doped, charge carrier recombination is minimal.
