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

A

electrons crossover form emitter to collector

B

holes move from base to collector

C

eelctrons move from emitter to base

D

electrons form emitter move out of base without going to the colelctoer

Text Solution

Verified by Experts

In an n-p-n transistor when the base emitter junction is forward biased and collector base junction is reverse biased electrons will move from and remaining will crosssover from emitter to collector
