High Capacitance: Spherical capacitors can have relatively high capacitance values compared to parallel-plate capacitors with the same surface area. This is because the electric field is concentrated near the surfaces of the spheres, allowing for efficient charge storage.
The length of the cylinder is L. When the capacitor is charged the inner cylinder holds +Q charge and the outer cylinder holds – Q charge. To calculate the electric field between two conductors using Gauss’ law, consider a Gaussian surface with radius r and length L1. Flux across the surface according to Gauss’ law is;
• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.
Uniform Electric Field: In an ideal spherical capacitor, the electric field between the spheres is uniform, assuming the spheres are perfectly spherical and the charge distribution is uniform. However, in practical cases, deviations may occur due to imperfections in the spheres or non-uniform charge distribution.
As a third example, let’s consider a spherical capacitor which consists of two concentric spherical shells of radii a and b, as shown in Figure 5.2.5. The inner shell has a charge +Q uniformly distributed over its surface, and the outer shell an equal but opposite charge –Q. What is the capacitance of this configuration?
In each plate of the capacitor, there are many negative and positive charges, but the number of negative charges balances the number of positive charges, so that there is no net charge, and therefore no electric field between the plates.
