A closed set of transport equations with collision terms that have been evaluated by the 13-moment approximation is used, under well-defined assumptions, to derive a generalized Ohms Law in multicomponent non -isothermal plasmas as a function of the electric and magnetic fields and the temperature and pressure gradients. The nine coefficients defining this dependence are expressed in matrix form in terms of component properties for any number N of components in the plasma, each component having its own temperature. The matrix expressions are evaluated in detail for four- and five-component plasmas N4,5 this allows the investigation of effects that cannot be studied with the available three-fluid expressions.
