Solid-state transistors, in turn, enabled technologies like the transistor radio, which took over a field once dominated by technologies like the cat's-whisker detector. Indeed, by the 1950s, ...

A transistor is a tiny but powerful electronic component that acts like a switch or an amplifier. It is made from a semiconductor material, usually silicon, and has three legs for connection to ...

How Do Transistors Work? At its core, a transistor is an electronic gatekeeper. It controls the flow of electric current through a semiconductor material. Most transistors have three terminals, often ...
