DIRECTCURRENT
Direct current
Direct current is the unidirectional flow of electric charge. Direct current is produced by sources such 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 flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current . A term formerly used for direct current was galvanic current.The above text is a snippet from Wikipedia: Direct current
