In P type substances, the charge carriers in minorities are:
Correct answer: B. Electrons
- A. Holes
- B. Electrons
- C. Protons
- D. Positive ions
Explanation
Minority charge carriers are those charge-carrying units in a substance that are very few in quantity. In p-type semiconductors, a very small number of free electrons is present. Hence, electrons are the minority charge carriers in the p-type semiconductor. In P-type semiconductors, holes are the majority charge carriers and electrons are the minority charge carriers.

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.
