Researchers explain why weak magnetic fields can instantly control electrical flow direction in these quantum metals. (Nanowerk News) Quantum metals are metals where quantum effects—behaviors that ...

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 ...

Electricity doesn’t just flow freely in every direction—it needs control. That control comes from a tiny but powerful ...

Large-scale currents are the conveyor belts of the ocean, transporting water and nutrients and controlling Earth's climate.

A direct current flows in only one direction. On a voltage-time graph this would appear as a straight horizontal line at a constant voltage. Car batteries, dry cells and solar cells all provide a ...

If you are an EE you definitely know the answer to this, or at least you think you do. If you said positive to negative, you are wrong. Then you remember that current flow is a charge of electrons ...

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 ...
