19.5 Capacitors and Dielectrics
A capacitor is a device used to store electric charge. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators. Typically, commercial capacitors have two conducting parts close to one another, but not touching, such as those in Figure 19.13. (Most of the time an insulator is used between the two …
Relative permittivity
Temperature dependence of the relative static permittivity of water. The relative permittivity (in older texts, dielectric constant) is the permittivity of a material expressed as a ratio with the electric permittivity of a vacuum.A dielectric is an insulating material, and the dielectric constant of an insulator measures the ability of the insulator to store electric energy in an …

Permittivity
In electromagnetism, the absolute permittivity, often simply called permittivity and denoted by the Greek letter ε (), is a measure of the electric polarizability of a dielectric material. A material with high permittivity polarizes more in response to an applied electric field than a material with low permittivity, thereby storing more energy in the material.
