Find the electric potential energy stored in the capacitor. There are two ways to solve the problem – by using the capacitance, by integrating the electric field density. Using the capacitance, (The capacitance of a spherical capacitor is derived in Capacitance Of Spherical Capacitor .) We’re done.
The capacitance for spherical or cylindrical conductors can be obtained by evaluating the voltage difference between the conductors for a given charge on each. By applying Gauss' law to an charged conducting sphere, the electric field outside it is found to be Does an isolated charged sphere have capacitance? Isolated Sphere Capacitor?
5.6 Spherical Capacitor from Office of Academic Technologies on Vimeo. 5.06 Spherical Capacitor A spherical capacitor consists of two concentric spherical conducting plates. Let’s say this represents the outer spherical surface, or spherical conducting plate, and this one represents the inner spherical surface.
The equivalent capacitance for a spherical capacitor of inner radius 1r and outer radius r filled with dielectric with dielectric constant It is instructive to check the limit where κ , κ → 1 . In this case, the above expression a force constant k, and another plate held fixed.
The system can be treated as two capacitors connected in series, since the total potential difference across the capacitors is the sum of potential differences across individual capacitors. The equivalent capacitance for a spherical capacitor of inner radius 1r and outer radius r filled with dielectric with dielectric constant
C = 4 π ϵ 0 (1 R 1 − 1 R 2) − 1. It is interesting to note that you can get capacitance of a single spherical conductor from this formula by taking the radius of the outer shell to infinity, R2 → ∞. R 2 → ∞. Since we will have only one sphere, let us denote its radius by R. R. C single sphere = 4πϵ0R. C single sphere = 4 π ϵ 0 R.
