Electrons present in p-type material due to thermal pair generation are_____________?
Correct answer: B. minority carriers
- A. majority carriers
- B. minority carriers
- C. dual carriers
- D. blockers
Explanation
In p-type material, holes are introduced as the majority carriers, while electrons produced by thermal generation are present in much smaller numbers and are therefore minority carriers. The likely mistake is choosing majority carriers by thinking that every thermally generated electron contributes equally, without considering the dominant hole concentration in p-type material.

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.
