The interest in the study of the superficial charges's distribution on the conductors that transport a current and its utility for the conceptual comprehension of the circuits's behavior have been increased recently. Numerous works and texts present numerical, analytic, and qualitative results for different geometries of the circuit's structure. The analytic results for a simple circuit formed by rectangular plates are presented here. This geometry permits to determine not only the distribution of the superficial charges that create the field in the interior of the conductors, but also the flow of energy that is directed since the source to the resistive elements of the circuit.
