Two pieces of aluminum and copper wire are identical in length and diameter. At some temperature, one of the wires will have the same resistance that the other has at 20oC.
(a) What is that temperature?
(b) If the two wires are connected in series, compute the ratio of the total resistance initially to the total resistance at the temperatures in part (a).
(c) Repeat part (b) if the wires were instead connected in parallel.
