For some applications, it is important that the value of a resistance not change with temperature. For example, suppose you made a 1.8 kΩ resistor from a carbon resistor and a Nichrome wire-wound resistor connected together so the total resistance is the sum of their separate resistances. The temperature coefficients of resistivity of carbon and Nichrome at 20∘C are -0.0005 (∘C)−1 and 0.0004 (∘C)−1, respectively. 1. What value should the carbon resistor have (at 20∘C) so that the combination is...
