Dielectric Constant (Dk)
The dielectric constant (Dk) of a plastic or dielectric or insulating material can be defined as the ratio of the charge stored in an insulating material placed between two metallic plates to the charge that can be stored when the insulating material is r, ,These are typically reported as dielectric constant (Dk) or ε', and the loss factor.
