Introduction to Capacitors, Capacitance and Charge
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. ...

The Capacitance of a Spherical Conductor Consider a sphere (either an empty spherical shell or a solid sphere) of radius R made out of a perfectly-conducting material. Suppose that the sphere has a positive charge q and that it is isolated from its surroundings. We ...
A spherical capacitor is another set of conductors whose capacitance can be easily determined (Figure 8.6). It consists of two concentric conducting spherical shells of radii …

5.06 Spherical Capacitor
The story of capacitors begins in the 18th century. It was a time of wigs, quills, and the birth of a new kind of electrical device. The earliest capacitors were known as Leyden jars, created around the 1740s. These were simple glass jars filled with water and lined with ...
