Zusammenfassung

Wiedemann-Franz law is a prediction of electronic theory of electric and thermal conductivity in metals, which states that a Lorenz ratio \$L=\kappa/(T)\$, where \$\kappa\$ is a thermal conductivity, \$\sigma\$ --- electric conductivity and \$T\$ --- absolute temperature, is a universal constant in certain cases. We present here a simple experimental setup to verify this prediction in a teaching experiment.
