Answer:
A Quantity measuring the ability of a substance to store electrical energy in an electric field is known as Dielectric constant.
Explanation:
The dielectric constant (k) of a material is the ratio of its permittivity ε to the permittivity of vacuum ε o , so k = ε / ε o. The dielectric constant is therefore also known as the relative permittivity of the material. ... Given its definition, the dielectric constant of vacuum is 1
