Spherical Capacitor. 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.

A capacitor is a passive two-terminal electrical component that stores potential energy in an electric field. The effect of a capacitor is known as capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit. 

Capacitance of spherical capacitor equation:

C = 4 * π * ε0 * εk / (1/a - 1/b)

where:
C - capacitance measured in farads (symbol: F)
a - radius of the inner sphere
b - radius of the outer sphere
ε0 - vacuum permittivity - a constant value of 8.85 × 10^(−12) F/m (farads per meter)
εk - relative permittivity. It is dimensionless
