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.
In DC circuits, the electricity is always the same polarity, which means that in a two-wire circuit, one wire, or side of the circuit, is always negative, and the negative side is always the one that sends the electricity.
