An electric current in which the flow of electric charge is consistently in one direction.
An electric current in which the flow of electric charge is consistently in one direction. Cells and batteries supply a direct current, which flows around the circuit in a single direction only. The current supplied by mains electricity is an alternating current, which means it continuously reverses direction. Phone chargers convert this into a direct current, which can be stored by the phone's battery.
