Insulator (electricity) - Wikipedia(electric)An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.This contrasts with other materials, semiconductors and conductors, which conduct electric current more easily.
