Main Question or Discussion Point

Is "Current" a vector quantity?

Is "Current" a scalar quantity? If yes then how? Because what I know is this: "Current is the quantity which has some particular direction i.e. from higher potential electrode to the lower potential electrode. Here it has both magnitude and direction, so it should be a vector quantity".

Current is a vector in electromagnetics/electrodynamics, a scalar in time-dependent circuit theory, and a complex phasor in time harmonic and laplacian (complex frequency) circuit theory.
