The dielectric loss, proportion of energy lost in the form of heat, is a measure of the efficiency of the dielectric. The lower the dielectric loss, the more effective is the dielectric material. The dielectric constant of a material can be defined as: the tendency of a material to resist the flow of an electric current across the material.
