Question

Is a transistor a switch?

Answer 1

A transistor works when the electrons and the holes start moving across the two junctions between the n-type and p-type silicon. ... By turning a small input current into a large output current, the transistor acts like an amplifier. But it also acts like a switch at the same time.Sep 21, 2020

Applications I: Switches. One of the most fundamental applications of a transistor is using it to control the flow of power to another part of the circuit -- using it as an electric switch. Driving it in either cutoff or saturation mode, the transistor can create the binary on/off effect of a switch.
