A device having high electrical resistance and used for supporting or separating conductors to prevent undesired flow of current from them to other objects. Also known as electrical insulator.
A material that is a poor conductor of heat, sound, or electricity.
A substance in which the normal energy band is full and is separated from the first excitation band by a forbidden band that can be penetrated only by an electron having an energy of several electronvolts, sufficient to disrupt the substance.
A component or device made from material having great enough resistance to the flow of electric current to be effectively considered as a nonconductor of current.
