Direct current (DC)

Direct current (DC) is that the unifacial flow of electrical charge. electrical energy is created by sources like batteries, power providers, thermocouples, star cells, or dynamos.

electrical energy could flow during a conductor like a wire, however also can flow through semiconductors, insulators, or perhaps through a vacuum as in lepton or particle beams.

the electrical current flows in a constant direction, distinctive it from electrical energy (AC). A term at one time used for this kind of current was galvanic current.



The abbreviations AC and DC area unit typically want to mean merely alternating and direct, as once they modify current or voltage.

Direct current could also be obtained from associate degree electrical energy offer by use of a rectifier, that contains electronic components (usually) or mechanical device components (historically) that enable current to flow solely in one direction.

electrical energy could also be reborn into electrical energy with an associate degree electrical converter or a motor-generator set.

Direct current is employed to charge batteries and as power offer for electronic systems. terribly giant quantities of direct-current power area unit utilized in the production of atomic number 13 and different chemical science processes.

it’s additionally used for a few railways, particularly in urban areas. High-voltage electrical energy is employed to transmit giant amounts of power from remote generation sites or to interconnect electrical energy power grids.
