The transistor proved to be a viable alternative to the electron tube and, by the late 1950s, supplanted the latter in many applications. Its small size, low heat generation, high reliability, and low power consumption made possible a breakthrough in the miniaturization of complex circuitry.
Aunque su definición básica cabe en una frase, su alcance es enorme: un transistor controla o modifica el flujo de corriente entre dos terminales atendiendo a una señal aplicada en un tercer terminal.
AS Mexico: ¿Quién era Nikola Tesla, el padre de la corriente alterna?
Corriente alterna contra corriente continua, podría ser el gran titular para comenzar a profundizar en esta batalla para ver quién se hacía con el dominio. Nikola Tesla y George Westinghouse apostaban ...
A transistor may have only one kind of charge carrier in a field-effect transistor, or may have two kinds of charge carriers in bipolar junction transistor devices. Compared with the vacuum tube, transistors are generally smaller and require less power to operate.
A transistor is a semiconductor that amplifies or switches electronic signals. Transistors serve as the basic building blocks of modern electronics.

Bardeen and Brattain made the first practical transistor (known as a point-contact transistor) on Tuesday, . Photo: A replica of Bardeen and Brattain's point-contact transmitter.
The advantage of a transistor is that you can use a small current or voltage to control a much larger current and voltage. That’s super useful if you want to control things like motors, high-power LEDs, speakers, relays, and more from a Raspberry Pi/Arduino/microcontroller.
