The degree to which a medium resists the flow of electric charge, defined as the ratio of the electric displacement to the electric field strength. It is more common to use the relative dielectric con [..]

A dimensionless parameter expressing the ratio of the permittivity of a material to that of vacuum. Metals have an infinite dielectric constant while gases and vapors have a dielectric constant close [..]

The ratio of the capacitance of a condenser with dielectric between the electrodes to the capacitance when air is between the electrodes. Also called Permittivity and Specific Inductive Capacity.

The ratio of the capacity of a condenser made with a particular dielectric material to the capacity of the same condenser with air as the dielectric. Measured at a frequency of 106 cycles per second. [..]

The ratio of the capacitance with a particular material separating the plates of a capacitor to the capacitance with a vacuum between the plates.

Property of a material representing the ability to store electromagnetic energy.

 - A number that describes the dielectric strength of a material relative to a vacuum, which has a dielectric constant of one.

The ratio of the capacitance of the insulated wire to that of the same wire uninsulated in air.

Used to determine the ability of an insulator to store electrical energy. The dielectric constant is the ratio of the capacitance induced by two metallic plates with an insulator between them to the c [..]

see "K" Constant (capital "K"!)

A measure for the effect of a medium on the potential energy of interaction between two charges. It is measured by comparing the capacity of a capacitor with and without the sample present. dienophile The olefin component of a Diels-Alder reaction. See cycloaddition

Illustrated Glossary of Organic Chemistry Dielectric constant (ε): A measure of a substance's ability to insulate charges from each other. Taken as a measure of solvent polarity, higher ε means h [..]

The ratio of the capacitance of a condenser with dielectric between the electrodes to the capacitance when air is between the electrodes.  Symbol:  K.

Property of a material that determines how much electrostatic energy can be stored per unit volume when unit voltage is applied.

The dielectric constant is the ratio of the permittivity of a substance to the permittivity of free space. It is an expression of the extent to which a material concentrates electric flux, and is the electrical equivalent of relative magnetic permeability.

A measure of the ability of a material to store charge when an electric field is applied.

The ratio of a given dielectric to the dielectric value of air. The property of an insulation which determines the electrostatic energy stored per unit volume for unit potential gradient. That propert [..]

Relative permittivity. It is the ratio of the capacitance of a capacitor with the given material as dielectric, to the capacitance of the same capacitor with vacuum (or air) as the dielectric.
