Electric Current:

Electric current is a physical quantity that measures the flow of charge. The electric current through the surface (real or imaginary) is defined as the net charge that crosses the surface in a unit interval of time.

Although the flow of charge has a direction, the electric current is not a vector quantity but is a scalar.
