Electricity doesn’t just flow freely in every direction—it needs control. That control comes from a tiny but powerful ...

A diode may look small, but it plays a crucial role in controlling how electricity flows. This video explains how diodes ...

Diodes are one of the most important parts of any electronics project, and if you don't understand how they work you'll destroy any electronics project you work on. Thankfully, Adafruit has a video ...

LEDs form an inevitable part in the modern electronics as simple indicators to optical communication devices. Light Emitting Diodes exploit the property of the p-n junction to emit photons when it is ...

How does a varactor diode work? To form the PN junction that makes a diode, half the piece is doped with a trace amount of “donor atoms” that have one more electron than the intrinsic stuff to make ...

And here it is, modelled using LTSpice. It is the same circuit as the classic simple precision rectifier (set to pass the negative half-sine), but with the non-inverting input of the op-amp connected ...

Some groups have coaxed modest numbers of electrons through plastics using quantum mechanical effects, but only by painstakingly manipulating individual molecules at cryogenic temperatures. But a ...
