The results of the calculations of the equilibrium potential and surface charge distribution in a vesicle with radii r1=55 A and r2=100 A are presented. The calculations were carried out for the electrolyte concentrations 100 mM, 10mM, 1mM and 0.1 mM. The digitally obtained solutions of the Poisson-Boltzman equation for the case of spherical symmetry were utilized in the exact solution of the problem. The predictions of the exact solution differ significantly from these of the linear approximation in the range of low electrolyte concentrations. The influence of the membrane dielectric permeability on the charge distribution is negligible.
