When npn transistor is used as an amplifer (a) electrons move from collector to base (b) holes move from emitter to base (c) electrons move from base to collector (d) holes move from base to emitter

Answer: (c). In an n-p-n transistor, electrons are the majority carriers in the emitter. They are injected from emitter into the base, then most cross from base to collector. So the answer is (c) electrons move from base to collector.

Junction Transistor

When $npn$ transistor is used as an amplifer

Show answer and solution

Answer: (c)

In an n-p-n transistor, electrons are the majority carriers in the emitter.
They are injected from emitter into the base, then most cross from base to collector.
So the answer is (c) electrons move from base to collector.
