The Wiedemann–Franz law is a principle in solid-state physics and materials science that relates the electrical conductivity of a metal to its thermal conductivity. It states that the ratio of the thermal conductivity (\\(K\\)) to the electrical conductivity (\\(\\sigma\\)) of a metal is proportional to the temperature (\\(T\\)).
