Conductor is a material easy to conduct an electrical charge, sedankan insulator is a substance that is difficult to conduct electrical charges. It has been stated earlier that at some electrons around this is easy to move and move.
In materials that are conductors of electrons on each atom are not tied tightly so that the electrons can move within the atom. Free electrons is what causes the material easy to experience or drain conductor of electric charge. Almost all types of metals such as silver, aluminum and copper are good konsuktor. Almost all non-metallic materials except the carbon is very difficult even at all does not conduct electrical charges.
