Unidirectional flow of electric charge

"DC power" redirects here. For the association football club, see DC Power FC.

Direct current (DC) is one-directional flow of electric charge.

An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams.

How is alternating current produced

The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current.^[1]

The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.^[2][3]

Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction.

Direct current may be converted into alternating current via an inverter.
