When NPN transistor is used as an amplifier

Options

  1. Aelectrons move from base to collector
  2. Bholes move from emitter to base
  3. Celectrons move from collector to base
  4. Dholes move from base to collector

Correct answer

A. electrons move from base to collector

Step-by-step solution

Elelctrons of n -type emitter moves from emitter to base and then base to the collector when NPN transistor is used as an amplifier.
