A 120-V generator is run by a windmill that has blades 2.0 m long. The wind, moving at 12 m/s , is slowed to 7.0 m/s after passing the windmill. The density of air is 1.29 kg/m 3 . If the system has no losses, what is the largest current the generator can produce? (Hint : How much energy does the wind lose per second?) Thank you very much...
