This document describes an experiment to determine the thermal and electrical conductivity of metal rods. The experiment involves measuring the thermal conductivity of copper and aluminum rods using a method that calculates heat flow through the rod. It also involves measuring the electrical conductivity of copper and aluminum by taking voltage and current measurements. The results for copper and aluminum are reported and compared to literature values. The Wiedemann-Franz law relating thermal and electrical conductivity is also tested by calculating the Lorenz number.
