Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light. Last ...

You know them, you love them, you take them for granted – they are single push button on/off switches. As [Dino] explains in the most recent episode of his Hack a Week series, they are typica… ...

NPN transistors are key components in electronics, used as switches or amplifiers with three legs: base, collector, and emitter. Thyristors are semiconductor switches with three legs: gate, anode ...

Analog switches can do the job if applied correctly, but lack the audio range required in professional line and level applications, may be subject to crosstalk between sections and are also very ...

A transistor acts as a switch, converting electrical inputs into output signals via logic gates. Now, Drew Endy (pictured) at Stanford University in California and colleagues have designed a ...

The transistor's substrate is sort of like a magic wire that can either conduct electricity or not, and the gate is the switch that controls whether the wire will conduct or not.

This quantum electronics component switches electrical current by controlled repositioning of a single atom, now also in the solid state in a gel electrolyte.

Transistors are the basic components of electronic circuits and are used in a variety of applications, including electronic switches and current amplifiers.
