This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

Electromagnetic waves with frequencies between microwave and infrared light, also known as terahertz radiation, are leveraged ...

[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 ...

Expensive semiconductor laser diodes have no tolerance for fast voltage or current transients. To minimize the risk of damage, a standard JFET-clamp circuit shorts the laser when there is no supply ...

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 ...
