the ratio of thermal to electrical conductivity is:
( 22/7^2 / 3 ) * ( (k/e)^2 ) * T
the value of the constant multiplying T being: 2.45x10-8 W-ohm-K-squared.

The Wiedemann-Franz law states that the ratio of thermal conductivity to the electrical conductivity of a metal is proportional to its temperature. The law can be explained by the fact that free electrons in the metal are involved in the mechanisms in both heat and electrical transport.
