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.

6 FAQs about [Surface charge distribution of a spherical capacitor]

What is an example of a spherical capacitor?

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?

How to calculate capacitance of a spherical capacitor?

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\).

Why do sphere capacitors have high capacitance?

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.

What is the charge on a spherical capacitor?

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?

What does it mean when a spherical capacitor is earthed?

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.

What is a uniform electric field in a spherical capacitor?

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.
