An electric current can flow freely in a conductor where as in an insulator it does not allow charges to move freely and thus electric current do not conduct. Metals such as copper typify conductors, while most non-metallic solids such as plastics, paper, rubber, glass are said to be good insulators, having high resistance to the flow of charge through them.

Detailed Description for INSULATOR

A perfect insulator does not exist, because even insulators contain small numbers of mobile charges (charge carriers) which can carry current. In addition, all insulators become electrically conductive when a sufficiently large voltage is applied that the electric field tears electrons away from the atoms. This is known as the breakdown voltage of an insulator. Some materials such as glass, paper and Teflon, which have high resistivity, are very good electrical insulators. A much larger class of materials, even though they may have lower bulk resistivity, are still good enough to prevent significant current from flowing at normally used voltages, and thus are employed as insulation for electrical wiring and cables. Examples include rubber-like polymers and most plastics.
