An electric motor operates a pump that irrigates a farmer’s crop by pumping 10 000 L of water a vertical distance of 8.0 m into a field each hour. The motor has an operating resistance of 22.0\Omega and is connected across a 110-V source.

1. What current does it draw?

2. How efficient is the motor?
