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...

Imagine that you have two pieces of different types of metal of the same mass. You then perform the following experiment. You take 500 ml of water in a well-insulated beaker with a diameter of 75 mm at 20.0+/-0.05°C. The two masses are heated to 100 +/- 0.05°C. Metal A is place in the water container. After waiting some time, you find that the temperature of the system stabilizes at 24.8+/- 0.05 °C. You then add metal B to the...

28. Wires of the same length are made from metals A and B. Metal A ha a coefficient of linear expansion equal to twice that of metal B. Both wires are heated independently, but uniformly from an initial temperature of 40 degrees celcius and the heating is stopped when their final lengths are again equal. If wire A is removed from the heat source when its final temperature is 50 degrees celcius, what is the final temperature of wire B?...
