The equivalent capacitance for a spherical capacitor of inner radius 1r and outer radius r filled with dielectric with dielectric constant It is instructive to check the limit where κ , κ → 1 . In this case, the above expression a force constant k, and another plate held fixed. The system rests on a table top as shown in Figure 5.10.5.
As mentioned earlier capacitance occurs when there is a separation between the two plates. So for constructing a spherical capacitor we take a hollow sphere such that the inner surface is positively charged and the outer surface of the sphere is negatively charged. The inner radius of the sphere is r and the outer radius is given by R.
The capacitance is directly proportional to the product of these radii and inversely proportional to their difference. As the radius of the inner sphere increases or the gap between the spheres decreases, the capacitance of the spherical capacitor will increase.
