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...

A wire with a radius R = .89 mm and length 45 cm is made of two materials, Carbon and Nichrome (resistivity not given I assume it needs to be googled). The Carbon portion is 15 cm long. The temperature of the wire is 75 oC. The wire is connected to a 12 volt battery. a) Find the total Resistance of the battery as well as the current (I) and the current density (J) and the electric field (E) in...
