For some an application, it is important that the value of a resistance not change with temperature. We want to make a 4.70-kO resistor from a carbon and Nichrome wire-wound resistor conected together so the total resistance is the some of their separate resistances. What value of should each of these resistors have ( at 0 °C) so that the combination is temperature independent?

I thank you in advance.
