These things use dc:
batteries provide direct current, so anything run by batteries;
electrolysis, used for electroplating, aluminium manufacture and the production of sodium hydroxide.
Simply, direct current (DC). The amount of current depends on the circuit it is used in.
OneDirection = direct current OppositeDirection = alternating current Source=physics lessons and gives exams :)
AnswerThere is a hard rock band called AC/DC .In electrical jargon, AC is short for alternating current and DC is short for Direct current.
AC is alternating current like in your house. DC is direct current like in your car.
Alternating current direct current 1973
Alternating current. Direct current is used in batteries.
DC are the letters for direct current AC are the letters for alternating current
DC are the letters for direct current AC are the letters for alternating current
An example of direct current is the current used from a car battery to activate the starter motor. Also the flashlight uses direct current.

Direct Current or DC
An inverter
No. Transformers are used in circuits with Alternating Current. Transformers work on the principle of a "changing" magnetic field inducing a current in a conductor, and you don't get that "changing" field with Direct Current.
Rectifier is used to convert alternating current to direct current.
Direct current.
Electricity is used. It is stored in the form of DC voltage. DC is direct current which is not what is used in your home. DC is used in storage batteries. AC or alternating current is what is used to power your home.
Direct current (DC or "continuous current") is the unidirectional flow of electric charge. Direct current is produced by such sources as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type. Direct current may flow in a conductor such as a wire, but can also be through semiconductors, insulators, or even through a vacuum as in electron or ion beams. In direct current, the electric charges flow in the same direction, distinguishing it from alternating current (AC). A term formerly used for direct current was Galvanic current. Direct current may be obtained from an alternating current supply by use of a current-switching arrangement called a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be made into alternating current with an inverter or a motor-generator set. The first commercial electric power transmission (developed by Thomas Edison in the late nineteenth century) used direct current. Because of the advantage of alternating current over direct current in transforming and transmission, electric power distribution today is nearly all alternating current. For applications requiring direct current, such as third rail power systems, alternating current is distributed to a substation, which utilizes a rectifier to convert the power to direct current. See War of Currents. Direct current is used to charge batteries, and in nearly all electronic systems as the power supply. Very large quantities of direct-current power are used in production of aluminum and other electrochemical processes. Direct current is used for some railway propulsion, especially in urban areas. High voltage direct current is used to transmit large amounts of power from remote generation sites or to interconnect alternating current power grids.
