A spherical capacitor consists of two concentric spherical conductors, separated by an insulating material known as a dielectric. The inner sphere is usually positively charged, while the outer sphere is negatively charged, creating an electric field between them. Imagine you have two shiny, metallic balls, one smaller and one larger.
Dielectric Medium: The space between the inner and outer spheres of a spherical capacitor is occupied by a dielectric material, serving a crucial role in the capacitor’s operation. This dielectric material functions to provide insulation between the two conductors while facilitating the formation of an electric field.
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.
Therefore, we find that the capacitance of the capacitor with a dielectric is C = Q0 V = Q0 V0 / κ = κQ0 V0 = κC0. This equation tells us that the capacitance C0 of an empty (vacuum) capacitor can be increased by a factor of κ when we insert a dielectric material to completely fill the space between its plates.
The field lines are perpendicular to the surfaces of the spheres and are stronger near the regions of higher charge density. Capacitance: The capacitance of a spherical capacitor depends on factors such as the radius of the spheres and the separation between them.
The system can be treated as two capacitors connected in series, since the total potential difference across the capacitors is the sum of potential differences across individual capacitors.
