Electrical Engineering XYZ MCQs
Electrons in p-type material of a semi-conductor are classified as:
- Minority carriers
- Valance carriers
- Majority carriers
- Either minority carriers or majority carriers
Correct answer: 1. Minority carriers

Explanation: In p-type semiconductor material, the majority carriers are “holes” (positively charged vacancies in the valence band), not electrons. This is because p-type semiconductors are doped with acceptor impurities, which create holes in the valence band that outnumber the free electrons.
