Electric current (I) through a given area of a conductor is the rate of flow of electric charge through the area.Conventionally the direction of electric current is taken along the direction of motion of positive charges.
For a quantity to be a vector: 1) it has to have magnitude and direction
2) it has to obey the laws of vector addition .
Current satisfies the first but fails the second therefore it is a scalar quantity.
i.e if two currents meet at a junction, the total current of the resultant will be the algebraic sum of the two current and not the vector sum.So even though current has direction, it is a scalar quantity.
