Current is measured in amperes (A), equivalent to coulombs per second (C/s). Current flows when there is an electric potential difference (voltage) between two points, and there are charge carriers that are free to move between those points. Electrical conductors (metals) contain electrons that are free to move. Electrons are the drifting particles in a current-carrying wire, but conventional current is defined as the direction that positive charge would flow.

Copper and silver atoms have loose electrons, making them good conductors. Current is measured by counting charges passing through a boundary per second. It also shows how saltwater conducts current with positive and negative ions moving in opposite directions.
