Resistivity of some material is given below. State which one will be the best conductor.

       

Material	Copper	Aluminium	Silver	Nickel
Resistivity (Ωm)	1.62 x 10 – 8	2.63 x 10 – 8	1.60 x 10 – 8	6.48 x 10 – 8

 From the above table we find that of all the metals, silver has the lowest resistivity (1.60 x 10 ^{– 8} Ωm), which means that silver offers the least resistance to the flow of current through it. Thus, silver metal is the best conductor of electricity.
