- Homework Statement:
- A spherical capacitor is formed by two thin conductive layers, spherical and concentric, of radius [itex] R_1 [/itex] and [itex] R_2>R_1 [/itex], between which we have placed a dielectric material of relative permittivity [itex] \varepsilon_r [/itex]. Knowing that the inner layer has an [itex] Q [/itex] charge, idetermines the capacity of the capacitor and the total energy stored.

- Relevant Equations:
- Gauss Law

When I try to do Gauss, the permeability is not always that of the free space, but it varies: up to a certain radius it is that of the void and then it is the relative one. How can I relate them? I'm trying to calculate the capacity of a spherical capacitor.

The scheme looks like this: inside I have the free space and between the plates of the capacitor I have the dielectric material.

The broken lines represent the Gaussian surface.
