A two wires, one of Copper and the other of Nickel, if the resistance of the first is (12.7 Q), and
the second is (11.6 0) at room temperature, at what temperature are their resistances equal?
Note that the temperature coefficient of resistivity of Copper is (0.0039 C-1), and for Nickel it is
equal to (0.006 C1).
