Researchers enhance conversion efficiency of thermoelectric devices

In the effort to reduce our reliance on fossil fuels, one strategy involves harvesting the waste heat that is already being produced by our energy systems. Thermoelectric generators can convert waste heat to clean electricity, ...

Electric current

Electric current is the rate of flow of electric charge. The electric charge that flows is carried by, for example, mobile electrons in a conductor, ions in an electrolyte or both in a plasma.

The SI unit of electric current intensity is the ampere. Electric current is measured using an ammeter.
