Electrical current

Education and science articles. A simple diagram of an electrical current flowing through a circuit

Electric current is defined as the flow or movement of electrons or electron-deficient atoms. It is represented by the upper case letter I and is measured in amperes represented by A. Current flows from relatively positive points to relatively negative points.

There are two kinds of electric current Alternate current (AC) and Direct current (DC).
