ResumoAbout some questions of Coulomb experiments; how did Coulomb ensure that during the measurements the charges in the spheres were held constant? How could he vary and accurately quantify the amount of charge in the sphere? How was the inductive effect affecting the charge distribution in the conductors considered?, effects producing deviations on the charge spherically symmetric distribution model of Coulomb law, have been resolved thanks to the current technology (High voltage power sources, high sensitivity scales), and the use of mathematical tools. In this paper we show the force convergence between conductors, on the main reported theoretical models, to the Coulombian equation; Uniqueness theorem and energy superposition principle (Purcell); Electrostatic energy (Landau); Method of image charges (Jackson); Maxwell method of images; Electrical power between conducting spheres evaluation by means of bispherical harmonic functions (Crown-Law).
