2) Calculate the resistivity of a manufactured "run" of annealed copper wire at 20°C, in ohms-circular mils/foot, if its conductivity is 96.5%. 3) A coil of annealed copper wire has 820 turns, the average length of which is 9 in. If the diameter of the wire is 32 mils, calculate the total resistance of the coil at 20°C. 4) The resistance of a given electric device is 46 ◊ at 25°C. If the temperature coefficient of resistance of the material is 0.00454 at 20°C, determine the temperature of the device when its resistance is 92 02.
