Problem
Electric current in a straight conductor is often specified along with the direction of flow of positive charge. How should electric current be classified?
(a) Vector, because its direction is essential to determine the net current in a circuit.
(b) Vector, because it can be resolved into perpendicular components.
(c) Scalar, because although it has a specified direction, it does not follow the rules of vector addition.
(d) Vector, because it must be expressed with a direction.
