Abstract
-
Electrical conductivity describes the ability of a material to transport charge through the process of conduction, normalized by geometry. Electrical dissipation comes as the result of charge transport or conduction. Dissipation or energy loss results from the conversion of electrical energy to thermal energy (Joule heating) through momentum transfer during collisions as the charges move.
-
Electrical storage is the result of charge storing energy. This process is dielectric polarization, normalized by geometry to be the material property called dielectric permittivity. As polarization occurs and causes charges to move, the charge motion is also dissipative.
