Direct current (DC) is a form of electric current that is uni-directional. So the flow of charge is always in the same direction. Among the given options, a DC generator, a solar cell, and a battery generate DC. An AC generator produces a current that alters its direction about 50 times a second, which is referred to as 'Alternating current'
