What Is A Capacitor & What Are The Various Types of Capacitors
Capacitors are simple passive devices which are used to store electricity. The capacitor has the ability or "capacity" to store energy in the form of an electrical charge producing a potential difference (Static Voltage) across its plates, much like a small rechargeable battery.
The standard examples for which Gauss'' law is often applied are spherical conductors, parallel-plate capacitors, and coaxial cylinders, although there are many other neat and interesting charges configurations as well. To compute the capacitance, first use
In a spherical capacitor, a solid or hollow spherical conductor is surrounded by a hollow circular conductor of a different radius. The formula of spherical capacitor: C = Q∆V = 4πo/(1 r1-1r2) Assuming C = Capacitance Q = Charge V = Voltage r1 = inner radius

8.1 Capacitors and Capacitance – University Physics Volume 2
Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage V across their plates. The capacitance C of a capacitor is defined as the ratio of the maximum charge Q that can be stored in a capacitor to the applied voltage V across its plates. ...
