The Wiedemann-Franz Law, named after German physicists Gustav Wiedemann and Rudolf Franz, is a ratio of the thermal to electrical conductivities of metals. In 1853, the two studied the thermal conductivity, a measure of a system's ability to transfer heat, of a number of elemental metals and found that the ratio of the thermal to electrical conductivities was approximately the same for different metals at the same temperature.read more
