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

A brief look at a twenty different diodes, their symbol variations, and a basic description. And yes, we're looking at tubes ...

To see a video on this topic by the author, click here. However, as the frequency increases; the current moves toward the outside of the conductor as indicated by the red and orange colors. This ...

Electric current comes in many forms: current in a wire, flow of ions between the plates of a battery and between plates during electrolysis, as arcs, sparks, and so on. However, here on Hackaday we ...

How a Virginia Tech research team constructed its novel thermal diode. Test results of the thermal diode. Electrical engineers are obviously very familiar and comfortable with the basic diode, a ...

Quantum metals are metals where quantum effects—behaviors that normally only matter at atomic scales—become powerful enough to control the metal's macroscopic electrical properties. Subscribe to our ...

Ferromagnets are characterized by a magnetization that has long been used to store information. The magnetization is largely due to localized electron spins with their associated magnetic moments ...

Higher-than-normal operating voltages give steppers better torque at high speeds — but watch that current! • The inductance in a stepper-motor phase winding limits how fast current rises when power is ...
