What value should the carbon resistor have (at 20 C) so that the combination is temperature independent? For some applications, it is important that the value of a resistance not change with temperature. For example, suppose you made a 90 Express your answer to one significant figure and include the appropriate units. kf 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) and 0.0004 ( C) , respectively.
