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 ...

Nearly every piece of technology you use—from smartphones to computers—relies on one revolutionary component: the transistor. In this video, you’ll learn how transistors work as electronic switches ...
