Current is a scalar quantity. In Watt-less current, we divide current into components like vectors. Moreover, when AC current passes through inductors or capacitors, we put a vector sign over current. Can anyone please elaborate?
In spatial terms current is a scalar. It is the dot product of current density and orientated area.
In ac theory, current may be treated as a vector, because its magnitude and phase can be treated as a vector which rotates continuously in an abstract 'space', not in the real space that we inhabit. It is a mathematical device.
