Quantum metals are metals where quantum effects—behaviors that normally only matter at atomic scales—become powerful enough ...

Shini explores electric current, voltaic cells, and how we get electric charge. Electric current works like a river... kinda... Instead of flowing based on elevation ...

This video explains the function of diodes and how they are used to control the flow of electrical current in electronic circuits. Diodes are essential components that allow current to move in only ...

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 ...

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 ...

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 ...

In school, you might have learned that electrons were negatively charged and protons were positive. This is not a fact of nature but a human-invented convention. It’s a fact that protons and electrons ...

Key learning points Electrical charges What are free electrons? Cell polarity Conventional current direction Electrons orbit the nucleus. An atom has a neutral charge, because it contains the same ...
