  We investigate equilibria of charged deformable materials via the
minimization of an electroelastic energy. This features the coupling of elastic
response and electrostatics by means of a capacitary term, which is naturally
defined in Eulerian coordinates. The ensuing electroelastic energy is then of
mixed Lagrangian-Eulerian type. We prove that minimizers exist by investigating
the continuity properties of the capacitary terms under convergence of the
deformations
