Question

What is the value of alpha for copper in terms of Fahrenheit degrees? If the resistance is a linear function on the Celsius scale, will it be a linear function on the Fahrenheit Scale? Explain. Replot the copper data for R_ c versus T with a smaller temperature scale extending to -300 degree C, and extrapolate the line to the temperature axis. At the what temperature would the resistance go to zero? What are the practical electrical implications for a conductor with zero resistance? It is interesting to note that the value of alpha is roughly the same for many pure metals: approximately 1/273 or 0.004 degree C^-1. This is the same as the value of the coefficient of expansion of an ideal gas. Also, some metals and alloys do become "superconductors." or have zero resistance, at low temperatures. Some "high-temperature" ceramic materials show superconductivity at liquid nitrogen temperatures (77 K, or -196 degree C, or -321 degree F).
