For some applications, it is important that the value of a resistance not change with temperature. For example, suppose you made a 3.60 −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.
a) What value should the carbon resistor have (at 0 ∘C) so that the combination is temperature independent?
b) What value should the Nichrome wire-wound resistor have (at 0 ∘C) so that the combination is temperature independent?
