WEBElectric current is a flow of electricity through a medium and its SI unit is the ampere, with the symbol A. The flow is typically through a wire and composed of electrons, the tiny particles that make up electricity. For most practical purposes the ampere is a measure of the amount of electric charge passing a particular point in a given time.
