Identify the correct statement about minority carriers_____________?
Correct answer: A. holes in n-type and free electrons in p-type
- A. holes in n-type and free electrons in p-type
- B. holes in n-type and p-type
- C. free electrons in n-type and holes in p-type
- D. free electrons in n-type and p-type
Explanation
In n-type material, electrons are majority carriers, so holes are minority carriers; in p-type material, holes are majority carriers, so electrons are minority carriers. Thus the minority carriers are holes in n-type and free electrons in p-type material. The likely mistake is choosing c, which reverses the majority and minority carrier roles.

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.
