Two ac generators supply the same voltage. However, the firstgenerator has a frequency of 1.5 kHz, and the second has afrequency of 6.4 kHz. When an inductor isconnected across the terminals of the first generator, the currentdelivered is 0.55 A. How much current isdelivered when this inductor is connected across the terminals ofthe second generator?
