Direct current (DC)

The video tutorial explains the difference between direct current (DC) and alternating current (AC). DC flows in one direction and is supplied by cells and batteries, while AC continuously reverses direction and is supplied by mains electricity. Phone chargers convert AC to DC for storage in phone batteries.
