The rate at which electric charge flows past a point in a circuit, measured in amperes (A).
Revise: Current, resistance and potential differenceA current is a flow of electric charge. A source such as a cell provides a potential difference, transferring energy to the charge and pushing it around a complete circuit. Components oppose that flow; this opposition is called resistance.
