15.
In an n-p-n transistor, the majority carriers in the base are
electrons
holes
both holes and electrons
either holes or electrons
Answer: Option
Explanation:

Emitter is n type and emits electrons which diffuse through the base.

No, it's wrong.

Because they are not intrinsic semiconductor so hey will have some potential to move but not exceeding the barrier potential.

@Esk Kishore.

Its hole is majority carriers in the base.

Sachin said:   8 years ago
Yeah, The given answer is wrong because in NPN transistor base is p and in p base, the holes are majority carrier.

P N P - means; + - +, Hole-Electron-Hole, Emitter-Base-Collector.

Aman said:   8 years ago
N P N - means; - + -, Electron-Hole-Electron; Emitter-Base-Collector.

Majority carrier must be holes.

Answer is B.

Bikash said:   8 years ago
@Dolan. You are wright answer should must be hole according to questions.

Holes are the majority carriers in the p region.

Chaithra said:   7 years ago
In the base, majority carriers should be holes. Right?

AJAY JOSHI said:   7 years ago
In transistor all major current are flow due to majority carrier so base is p type it has majority charge carrier is holes, so the answer should be holes.
