A 2.0-m length of wire is made by welding the end of a 120-cm-long silver wire to the end of an 80-cm-long copper wire. Each piece of wire is 0.60 mm in diameter. The wire is at room temperature, so the resistivities are as given in Table 25.1. A potential difference of 9.0 V is maintained between the ends of the 2.0-m composite wire.

An 80 cm long wire is made by welding a 1.8 mm diameter, 20 cm long copper wire to a 1.8 mm diameter, 60 cm long iron wire at normal room temperature (20 ∘C). When two wires are connected end to end, their resistances add together. The resistivity of copper is 1.68×10−8Ωm and the of iron is 1.00×10−7Ωm. The temperature coefficients are: copper = 0.0039/∘C and iron = 0.0050/∘C. What is the resistance of the iron section of wire?
