Question

when NPN transistor is used as amplifier​

Answer 1

❤hola ❤

NPN transistor is used as amplifier when electrons move from base to collector .

in NPN transistor electrons flow from emitter to be some of the electrons are neutralized by holes in the base and the remaining electrons move toward the collector .

Answer 2

Answer:

holes move from base to emitter

Step-by-step explanation:

When forward bias is applied on n-p-n transistor, then it works as an amplifier in forward biased n-p-n transistor, electrons move from emitter to base and holes move from base to emitter.
