[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 ...

A semiconductor diode is an electronic component that allows current to flow in only one direction, acting like a one-way valve for electricity. It is commonly used for voltage regulation, converting ...

The scientists are going to show us how electrical energy flows around an electrical circuit. Title: Circuit symbols This is what a battery looks like as a circuit symbol. Electricity can travel ...

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 ...

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 ...
