Bipolar Junction Transistors (BJT) - Technical MCQs

Q1:

Most of the electrons in the base of an NPN transistor flow:

A out of the base lead

B into the collector

C into the emitter

D into the base supply

ANS:B - into the collector

As electrons always flow from negative potential to higher potential though it is pnp or npn elctron will move from emitter to collector.
