An aluminum wire has a resistance of 4.00 0 at 32.090. Determine its resistance {in Q) at 432C. The temperature coefficient of resistivity for aluminum wire is 3.90 x 103 {C)_l- (Assume that the temperature coefficient of resistivity was measured using the reference temperature 20C.) x We are interested in two cases. For case 1. we know the resistance at some temperature and for case 2 we wish to determine the resistance at some other temperature. Write an expression for the resistance as a function of the temperature for each case and eiiminate Rs} between the two expressions in order to determine the resistance for case 2
