Answer:
For electric current, the directionality is only that along the wire (opposite to flow of electrons). In Summary, since the electric current doesn't follow the Triangular Law, it is not a vector. It is just a scalar quantity. [Another such quantity is Time.

Answer:
In the case of electric current, when two currents meet at a junction, the resultant current of these will be an algebraic sum and not the vector sum. Therefore, an electric current is a scalar quantity although it possesses magnitude and direction .
