Transistors, small devices that can amplify or switch electrical signals, are central components of all modern computer chips ...

A load switch is an electronic switch. It works like a relay to power supply rails in systems, but it has no moving parts. Load switches are increasingly found in today’s portable electronic devices, ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

For switching high-powered loads from a microcontroller, or for switching AC loads in general, most of us will reach into the parts bin and pull out a generic relay of some sort. Relays are ...
