Question

Explain three modes of operation of the transistor

Answer 1

there are four modes...and that are:
Saturation – The transistor acts like a short circuit. Current freely flows from collector to emitter.

Cut-off – The transistor acts like an open circuit. No current flows from collector to emitter.

Active – The current from collector to emitter is proportional to the current flowing into the base.

Reverse-Active – Like active mode, the current is proportional to the base current, but it flows in reverse. Current flows from emitter to collector (not, exactly, the purpose transistors were designed for)

Answer 2
