Campo Elétrico "na Superfície" de um condutor: Uma questão a ser esclarecida

Abstract

In this paper we deal with a classical problem in the context of high-school teaching: how the field behaveson the surface of a spherical conductor in electrostatic equilibrium? We argue that, due to the discontinuity of the field on the surface of the conductor, it cannot assume a unique value on the surface. © Sociedade Brasileira de Física.
