# Current divided into components like vectors [duplicate]

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?

• Well, not sure why you are sure that current is a scalar quantity. I may have forgotten undergraduate physics course, but as far as I know, one of the definitions of the current is $\vec{I} = \rho \vec{v}$, where $\rho$ is the charge density and $\vec{v}$ is the velocity of the charge drift. Check your phenomenology. Aug 4 '17 at 14:14

• Oh, ok, my bad... What I was referring to is current density. Thanks @CooperCape Aug 4 '17 at 14:52
