A transistor can be used as an amplifier or a switch. It has three parts: the base, the collector, and the emitter. It controls the gate of electricity to a much larger supply. It works sort of like your water faucet would when you turn it ...

Most introductory textbooks do a very poor job of explaining the details of how transistors work. First they assume that the Base current is somehow controlling the Collector current, then they try to explain how one current can affect another.

* This discussion relates to Bipolar transistors. Other types of transistor such as "FETs" (Field Effect Transistors) are in common use and work in a slightly different way in that the voltage applied to the "gate" terminal controls the current flowing from "cathode" terminal to "anode" terminal.

How does a transistor work? Asked by: Tony Whelan ; Answer; The design of a transistor allows it to function as an amplifier or a switch. This is accomplished by using a small amount of electricity to control a gate on a much larger supply of electricity, much like turning a valve to control ... How do transistors work?

Each transistor has a store of electrical charge that remains there until it is turned on. In order to turn on a transistor, a small electrical charge needs to enter it via the base. When this happens, the electrical charge opens up the col...

The audience to which it is aimed, is anyone who has or hasn't a clue to how these little Buggers work and/or how to use them. A real problem with some other explanations: ... The maximum input impedance one can expect from an emitter follower, is limited by the finite gains of individual transistors (~ 50 to ~ 350).

How do transistors work? ... Transistors work on the principle that certain materials e.g. silicon, can after processing be made to perform as "solid state" devices. Any material is only conductive in proportion to the number of "free" electrons that are available.
