  We develop an action principle to construct the field equations for a
multi-fluid system containing charge-neutral fluids, plasmas, and dissipation
(via resistive interactions), by combining the standard, Maxwell action and
minimal coupling of the electromagnetic field with a recently developed action
for relativistic dissipative fluids. We use a pull-back formalism from
spacetime to abstract matter spaces to build unconstrained variations for both
the charge-neutral fluids and currents making up the plasmas. Using basic
linear algebra techniques, we show that a general "relabeling" invariance
exists for the abstract matter spaces. With the field equations in place, a
phenomenological model for the resistivity is developed, using as constraints
charge conservation and the Second Law of Thermodynamics. A minimal model for a
system of electrons, protons, and heat is developed using the Onsager procedure
for incorporating dissipation.
