'''Direct Current''' (DC) is a voltage or current that does not vary with time.  It is the form in which electricity is generated by a chemical cell ([[battery]]), a [[solar cell]] ([[photovoltaic]]) or a DC [[generator]].  DC is not used for power transmission because it cannot be manipulated by a [[transformer]].
