An AC electric motor of average power P = 1.1 kW operates under root-mean-square voltage of Vrms = 220 V. The electric company charges 0.40 per kWh of energy. a) What is the root-mean-square current Irms through the motor while it runs? b) What is the equivalent resistance of this motor? e) How much would it cost to run it 4.0 hours a day, during 25 days a month?
