Electrons in a P-type substance due to thermal pair-generation are known as_.
Correct answer: B. Minority carriers
- A. Majority carriers
- B. Minority carriers
- C. P-type
- D. N-type
Explanation
In a P-type semiconductor, the electrons generated due to thermal pair-generation are considered minority carriers. These carriers are present in smaller numbers compared to the dominant carriers (holes) and play a crucial role in the conductivity of the semiconductor, even though they are not the majority charge carriers in this type of material.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
