electrical properties of materials It should not be confused with resistivity (ρ) - an intrinsic property of the material  which indicates how strongly it opposes the electric current.

Most ceramics and polymers, whose electrons are tightly bound by covalent and/or ionic bonding, are poor conductors. Many of these materials are used as insulators because they possess high resistivities. \u00a92010 John Wiley & Sons, Inc.
