This video explains what capacitors are and how they store and release electrical energy in electronic circuits. Capacitors ...

This video explains how LEDs (Light Emitting Diodes) function and why they are widely used in modern lighting and electronic ...

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 ...

[Hales] has been on a mission for a while to make his own diodes and put them to use and now he’s succeeded with diodes made of sodium bicarbonate and water, aluminum tape and soldered copper. By ...

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 ...

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.

Most plastics don't conduct electricity, though that hasn't stopped researchers from trying to build plastic computer chips. Some groups have coaxed modest numbers of electrons through plastics using ...

In the early hours of October 7, 2014, while most of America slumbered, members of the Swedish Academy of Sciences were meeting to decide to whom they should award the Nobel Prize in Physics. The ...
