In a transistor (npn), the emitter is:

Question

Accepted Answer

B. Heavily doped (to inject majority carriers efficiently)

**Emitter:** heavily doped
→ efficient injection of electrons (npn) into base.
**Base:** thin, lightly doped → minimal recombination.
**Collector:** moderately doped, larger
→ collects carriers and dissipates heat.

Answer

Same as collector

Answer

Insulating

Answer

Less doped than base
