Insulator (electricity) - Wikipedia

Electrical insulation is the absence of electrical conduction.Electronic band theory (a branch of physics) said that a charge flows if states are available into which electrons can be excited. This allows electrons to gain energy and thereby move through a conductor such as a metal.If no such states are available, the material is an insulator.
