Once again, we see that the capacitance C depends only on the geometrical factors, L, a and b. 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.
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 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).
Discharging of a capacitor. 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.
