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

This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in only one direction, making them essential for tasks like rectification, ...

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 ...

Unlike filament lamps, where electrical energy must be converted into heat before light can be produced, Light Emitting Diodes (LEDs) are able to transform electrical energy directly into light energy ...

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 ...

This very stern looking gentleman is about to explain how voltage doubles work in a plodding, yet satisfyingly thorough manner. We’re not certain when this US Air Training Command video was produced.
