2-hp single phase motor can be wired either 120/240 volts. The resistance is .4 ohm for each transmission wire connecting the motor source. If the motor was operating at 100% pf and eff and the cost of electrical power was $.10/kWh, how much can be saved each year if the motor was wired to the 240. Assume the motor has ran at full load for 8000 hrs and either the 120 or the 240 voltage drop is across the motor.
