A 120-V motor has mechanical power output of 3.00 hp. It is 83.0% efficient in convertingpower that it takes in by electrical transmission into mechanical power.

a) Find the current in the motor?
b) Find the energy delivered to the motor by electrical transmission in 2.00 h of operation.
c) If the electric company charges $0.160/kWh, what does itcost to run the motor for 2.00h ?
