- 6) In recent class lectures, we discussed the temperature dependence of the electrical resistivity, p(T) for the three main classes of materials that conduct an electrical current; conductors, semiconductors, and superconductors. In the graph below, draw in by hand examples of the temperature dependence of the electrical resistivity, pT), for each material type. Give at least one example of each material type. plT) + +>T(K) 100 200 300The quantity volt is equivalent to which of the following?
