Difference Between Conductor And Insulator Physics. Rubber Cotton are good examples of insulators. Insulators in contrast are made from materials that lack conduction electrons.
Charge flows only with great difficulty if at all. Differences between Conductor and insulators. Electrical conductors have zero or very little resistance while electrical insulators have very high or infinite resistance.
Conductors allow for charge transfer through the free movement of electrons.
Rubber Cotton are good examples of insulators. On the contrary if the potential difference of a sufficiently large voltage is applied across the insulator the applied electric field can tear away the electrons from the atoms of an insulator. This results in a large energy gap. The wire that carries electricity to your computer or television is covered with a rubber-like insulator that protects you from getting electrocuted.
