In an n-p-n transistor, the majority carriers in the base are
electrons
holes
both holes and electrons

In NPN transistor base is lightly dope with holes that's why holes are diffusion into electrons.

In non-transistor what are the current carriers inside and outside the transistor circuit?

Sajjanar said:   1 decade ago
Right @Kalal, the majority carriers in base are holes when transistor in ideal condition.

Gangadhar said:   6 years ago
Holes are majority charge carriers in p - region, irrespective of transistor action.

Vikram said:   7 years ago
The answer is B.

In transistor pnp, the base has electrons as charge carriers.

@Dolan. You are wright answer should must be hole according to questions.

Vishal gupta said:   1 decade ago
Answer must be holes according to question. So answer should be B part.
