Chapter 18 – DC (Direct Current) Circuits
However, in a circuit positive charge flowing in one direction is equivalent to an equal amount of negative charge flowing at the same rate in the opposite direction. In general, circuits in which charge flows in one direction are direct current (DC) circuits. In alternating current (AC) circuits (such as those in your house) the current direction

10.1 Circuits and current electricity
It is important to remind learners that circuit diagrams are just schematics of a circuit. When building a real circuit from a diagram, the real circuit will not look exactly the same as the diagram. A common misconception which develops in circuit building is that black wires carry negative current and red wires carry positive current.
Direction of current flow in a circuit
This happens if that potential has lesser value than some other node from which current is flowing. Assume a particular direction of current flow, write circuit equations in all meshes or nodes. If you get a negative value of current, then conclude that current was flowing in the opposite direction in that branch.
