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.
