IS CURRENT A SCLAR OR A VECTOR QUANTITY?
==> It may seem that current is a vector because it have a magnitude and a direction. But the thing is, a vector always obey the law of addition of vectors. Since current doesn't obey it and it follows algebraic addition, current is a scalar.
Also, Current is written as the dot product of Current Density vector and the Area vector.
I=J.A
