What is DC (Direct Current)?

Direct current (DC) is an electrochemical cell that is a great representation of DC power. Direct current may move through a conductor like a wire, but can also move through semiconductors, insulators, through a vacuum as in electron. Direct current has many utilizations, from the charging of batteries to huge power supplies for electronic systems, motors.
The direct current might be changed over from an alternating current supply by utilization of a rectifier, which contains electronic components that permit current to move only in one direction.
