Resistivity includes the following learning objectives:

  • Define resistivity;
  • Recall and use the expression for resistivity;
  • Use a practical method to determine the resistivity of a metal conductor;
  • Understand the effects of temperature on the resistance of a metal conductor and a semiconducting thermistor;
  • Understand that superconductivity is a property of certain materials which zero resistivity at certain temperatures;
  • State some applications of superconductors.
