This document details an experiment for measuring the frequency response of the impedance of cylindrical conductors, which is using a lock-in amplifier and the four-terminal sensing technique. Resistivity has been determined with high accuracy. Experimental results reveal the dependency of impedance on frequency, and the experimental data fit predictions derived from Maxwell-Faraday equations for a cylindrical conductor in a wide range of frequencies.
