Terry owns an electric vehicle that uses a 273 V DC electric motor. When Terry drives his vehicle on a 3.4 hour trip, the power used by the motor is a constant 16.7 kW.

If the power company charges Terry $0.12 per kWh, what is his total electric energy cost for the trip?

During the trip, what is the current used by the engine?

Answer #1

Energy used = Power*time = 16.7kW*3.4hr = 56.78 kWh

Cost = Energy used*rate=56.78kWh*$0.12/kWh = $6.8136

Current = power/voltage = (16.7*10^3)/273 = 61.17 A
