dielectric constant

- For a given material, the property which determines the
__electrostatic energy__that can be stored per unit volume for a unit__potential gradient__. This is__equivalent__to the__ratio__of the capacitance of a capacitor using the material in question as a dielectric, to the capacitance of a capacitor using a vacuum as a dielectric. The dielectric constant of a vacuum is defined as 1, and for most calculations air is also considered to have this__value__. Also known as relative dielectric constant, permittivity, relative permittivity, specific inductive capacity, or inductivity.
