When a straight wire is heated, its resistance changes according to the equation R= R[1 + a(T – To)] (Eq. 17.7), where a is the temperature coefficient of resistivity. (a) Show that a more precise result, which includes the length and area of a wire change when it is heated, is R,[1 + a(T - T)I1 + a'(T - T,)] [1 + 2a'(T – T,)] R = where a' is the coefficient of linear expansion. (See Topic 10.) (b) Compare the two results for a 2.00-m-long copper wire of radius 0.100 mm, starting at 20.0°C and heated to 100.0°C.
