We study a classical electrostatic problem presented in highschool and university textbooks: the electric field generated by a charge excess in a spheric conductor. Firstly, we verify the field value on the surface of the conductor, assuming the singular charge distribution model. Secondly, given some flexibility to the charge distribution to a uniform density over a tiny spherical shell, we show that apparent discrepancies that are presented in literature only give evidence of the limitations of the singular model on describing of the real object.
