An atom in an electric field has its distribution of electrons displaced with respect to the nucleus. The plates of the capacitor also have a surface charge, which we will call $sigma_{text{free}}$, because they can move "freely" anywhere on the conductor. This is, of course, the charge that we put on when we charged the capacitor.

Capacitance of Spherical Capacitor formula is defined as a measure of the ability of a spherical capacitor to store electric charge, which depends on the permittivity of the surrounding medium, the radius of the spherical shell, and the distance between the shell and the center of the sphere and is represented as C = (ε r *R s *a shell)/([Coulomb]*(a shell-R s)) or Capacitance =
A spherical capacitor is a type of capacitor formed by two concentric spherical conducting shells, separated by an insulating material. This configuration allows it to store electrical energy in the electric field created between the two shells, and its geometry makes it particularly useful in various applications requiring uniform electric fields and high capacitance values.

The presence of the +3q charge outside the shell does not affect the charge distribution on the inner surface of the shell.

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?
The formula for the capacitance of a spherical capacitor is: First, we need to define a Gaussian surface that encloses the inner sphere and passes through the point of interest between the spheres. A convenient choice is a spherical surface with radius r, where \ (\displaystyle R_1 < r < R_2\).
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.
Problem 5: A spherical capacitor with an inner radius ( r1 = 0.1 m) and an outer radius ( r2 = 0.2 m ) is connected to a potential difference of ( V = 50 V ). Calculate the charge on the capacitor. Therefore, the charge on the spherical capacitor is ( 354 pC). What is a spherical capacitor and how is it constructed?
When the inner sphere of a spherical capacitor is earthed, it means that the inner sphere is connected to the ground, which has a potential of zero. Any charge that was initially on the inner sphere is neutralized because the earth can supply or absorb an unlimited amount of charge.
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.
