Direct current means the unidirectional flow of electric charge. It is produced from sources such as batteries, power supplies, solar cells, thermocouples or dynamos. Direct current may flow in a conductor such as a wire, but can also flow through insulators, semiconductors, or vacuum as in electron or ion beams.
