Electric current is a scalar quantity. ... 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.

Explanation:
A physical quantity is vector when the quantity has magnitude and direction.If the quantity obeys the laws of vector addition then also
it is said to be a vector quantity.
In the case of the electric current,when two currents meet at a junction,the resultant current of these will be an algebraic sum not a vector sum.Therefore electric current is a scala r quantity,even if it possess both magnitude and direction.
