The correct order of resistivity of metals is Hg>Ni>W>Ag. The electrical resistivity is particularly im portant because it will determine its electrical performance and hence whether it is suitable for use in many electrical components. For example it will be seen that the resistivity of copper, the resistivity of aluminium and that of silver and gold determines where these metals are used
