Set 10 Problem 1 Temperature-Independent Resistor Combo For some applications, it is important that the value of a resistance not change with temperature. For example, suppose you made a resistor from a carbon resistor and a N iehrome wire-wound resistor Connected together so the total resistance RT is the sum of their separate resistances. What value should each of these resistors have [at 20 I'C) so that the combination is temperature independent? Express your answer in terms of R1- and the temperature coefcients of resistance of carbon ac and Nichrome aN (specied at 20 \"(5). Note that ac Or Nichmme RN = The total resistance of the series combination is simply the sum of the separate resistances. Use this fact to write an expression for RU], the resistance of the combination as a function of temperature T. How can you express the condition that R is independent of T at T = 20\"C? (Hint: The function RU) must have zero slope at T: 0). ~Remember that acStep by Step Solution
