Consider an n-p-n transitor with its base-emitter junction forward biased and collector base junction reverse biased. Which of the following statements are true?

A

Electrons crossover from emitter to collector.

B

Holes move from base to collector.

C

Electrons move from emitter to base.

D

Electrons from emitter move out of base without going to the collector.

Text Solution

Verified by Experts

The correct Answer is:
A, C
In common base connection, majority of electrons (nearly 95%) going from emitter to base, enter into collector. Thus, option (A) is correct.
In above case, small no. of electrons (nearly 5%), going from emitter to base, combine with the holes in base. Thus, option (C ) is also correct.
