The conductivity of a material is the ability of the material to allow current to flow through the material without any hindrance. We know that Silver exists in the purest form in nature. Metals conduct the best in their purest form. Hence Silver has the greatest conductivity among the three. Silver is followed by copper in this group. Copper has the second-best conductivity among the given three metals. Aluminium is also a good conductor but Aluminium falls only after copper in the case of conductivity, Aluminium has the least conductivity, Copper has more conductivity than aluminium and Silver has the maximum conductivity among the three.
