Differentiate between conductors and insulators.
|They allow electricity to pass through them.||They do not allow electricity to pass through them.|
|They have electric charges free to move.||They have electric charges which are not free to move.|
|When some charge is transferred to a conductor, it readily distributes over the entire surface.||When some charge is transferred to an insulator, it remains at the same place over the surface.|
|Most metals are conductors.||Most non-metals are insulators.|
