Dc Circuits. A circuit is a closed loop through which electrons can flow. A direct current (DC) circuit is a type of circuit with direct current (as opposed to alternating current) flowing through it. That is, in a DC circuit, the current flows in one direction.
Although DC stands for direct current, DC often refers to constant polarity. Under this definition, DC voltages can vary in time, as seen in the raw output of a rectifier or the fluctuating voice signal on a telephone line.
