Examples of which include aluminum oxide, porcelain, and air, for ten points, name this type of material which is a poor conductor of electricity, but an efficient supporter of electrostatic fields and is used in making capacitors.
The Ewald-Oseen Theorem explains the cancellation of the primary wave when light propagates through them. Characterized by its relative permittivity, they can be damaged if the electrostatic field and its corresponding voltage become large enough to induce current.
