Vol. I
The ability of a capacitor to store energy in the form of an electric field (and consequently to oppose changes in voltage) is called capacitance. It is measured in the unit of the Farad (F). Capacitors used to be commonly known by another term: condenser (alternatively spelled "condensor").
How do capacitors work?
When they sit in the electric field between two capacitor plates, they line up with their charges pointing opposite to the field, which effectively reduces it. That reduces the potential on the plates and, as before, increases their capacitance.

Introduction to Capacitors, Capacitance and Charge
The parallel plate capacitor is the simplest form of capacitor. It can be constructed using two metal or metallised foil plates at a distance parallel to each other, with its capacitance value in Farads, being fixed by the surface area of the conductive plates and the distance of separation between them.

18.5 Capacitors and Dielectrics
An electric field exists between the plates of a charged capacitor, so the insulating material becomes polarized, as shown in the lower part of the figure. An electrically insulating material that becomes polarized in an electric field is called a dielectric .
The Parallel Plate Capacitor
The direction of the electric field is defined as the direction in which the positive test charge would flow. Capacitance is the limitation of the body to store the electric charge. Every capacitor has its capacitance. The typical parallel-plate capacitor consists of two metallic plates of area A, separated by the distance d.

This transfer of charge sets up an electric field across the plates of the capacitor. Depending on the how much resistance is in series with the capacitor will determine how fast current can flow into and out of the capacitor''s plates. Capacitor Charge. The capacitor charge time, is dependent on the capacitor time constant.
