Consider two conducting hollow spheres of radius r=b and r=c > b. The inner sphere contains a spherical space charge with density ϱ [As/m3] and radius a < b – e, which is eccentrically positioned at a distance e from the center. The homogeneous permittivity in b < r < c is ε, while the permittivity in the remaining space is ε 0. The potential on the outer sphere at r=C is V 0.
