Define Kilogram or SI unit of mass
Kilogram: kg: The basic SI unit of mass that is the only SI unit still maintained by a physical artifact: a platinum-iridium bar reserved in the International Bureau of Weights and Measures at Sevres, France.
Dielectric is a material in which energy can be accumulated. Ideally, it is a non-conductor of electric charge like insulators, but an efficient supporter of electrostatic fields. The
