Review. When a straight wire is warmed, its resistance is given by R = R0,[1 + a(T T0)] according to Equation 27.20, where a is the temperature coefficient of resistivity. This expression needs to be modified if we include the change in dimensions of the wire due to thermal expansion. For a copper wire of radius 0.100 0 mm and length 2.000 m, find its resistance at 100.0C, including the effects of both thermal expansion and temperature variation of resistivity. Assume the coefficients are known to four significant figures.

As the temperature of a metal rod varies, so does the resistance and the dimensions of the rod. If a iron rod has a resistance of 2.78 Ω at 20.0°C, determine the resistance of the rod (in Ω) at 120°C by accounting for the changes in both the resistivity and the dimensions of the rod. The coefficient of linear expansion for iron is 4.50 ✕ 10−6 (°C)−1 and the temperature coefficient of resistivity is 4.50 ✕ 10−3 (°C)−1. Ω
