Question: suppose an electric car with a dc motor is powered...

Question details

Suppose an electric car with a DC motor is powered by a maximum current of 100A that is produced by a battery with a potential difference of 200V. The motor windings and other wires dissipate 3000W in the form of heat due to this current. The mechanical friction in the drivetrain loses an additional 10%. What power reaches the road? What is the overall efficiency η of this vehicle in the conversion of DC current to usable work?
