The heavily doped region of a transistor is called:
Correct answer: A. Emitter
- A. Emitter
- B. Base
- C. Collector
- D. Anyone can be heavily doped
Explanation
The heavily doped region is called the emitter. It plays a crucial role in the operation of the transistor by emitting majority charge carriers, either electrons or holes, into the base region. This emission helps control the flow of current through the transistor.

About PN Junction
A PN junction forms when p type and n type semiconductor regions meet, creating a depletion layer and a potential barrier. The topic covers forward and reverse bias, diode current voltage characteristics, breakdown and rectification, while distinguishing an ordinary junction diode from a transistor formed from multiple junctions.
