Too Cool to Resist

Authors: Allister McRae, Eric Smith
Lab Manual: PDF Download
Kit: Reserve
Previous title: Superconductivity, Too Cool to Resist

Abstract: Students will take measurements of the voltage across a copper resistor and a superconductor starting at room temperature. By controlling the amount of thermal contact with liquid nitrogen, students then measure the voltages down to approximately 77K. By graphing their results, they will see the effect of temperature on the resistance of a “normal” conductor, and the radically different effect on a superconductor. The lab ends with a demonstration of the Meissner Effect, a superconducting classic!
