A copper bar of resistivity 10.37 CM/ft at 20 C is 10 ft long. The dimension of the copper bar is 3 inches by 0.5 inches. If the inferred absolute zero temperature of copper is -234.5 C, determine the resistance of the bar at 27 C in microohm. Assume that the dimension of the bar is not affected by the change in temperature.
