Abstract
We study dielectric breakdown for composites made of two isotropic phases. We show that Sachs's bound is optimal. This simple example is used to illus trate a variational principle which departs from the traditional one. We al so derive the usual variational principle by elementary means without appea ling to the technology of convex duality.
