  1. Because current has no direction, simply a magnitude (strength) therefore is a scalar quantity.  For example 6 A.  (No direction listed)

    Current density is amps per square meter of cross-sectional area NORMAL to the current flow. It has a direction (normal, meaning at right angles to) and thus is a vector quantity.
