The Easiest Way to Understand a TRANSISTOR
The transistor is an electronic component which is used in most electronic circuits (logic circuits, amplifier, voltage stabilizer, signal modulation, etc.) both at low and high voltage.
A transistor is a semiconductor device with three active electrodes, which makes it possible to control a current or a voltage on the output electrode (the collector for the bipolar transistor and the drain on a field effect transistor) thanks to an electrode input (the base on a bipolar transistor and the gate for a field effect transistor).
The circuit being connected to the “collector” and “emitter” terminals, the transistor is insulating without voltage on the Base terminal, and conductive with a voltage on the Base terminal.
In other words, it is an electronically controlled switch, with no mechanical part.
