A 288.0 mH inductor is connected across the output terminals of an AC generator that is delivering an output voltage of 135.0 mV rms. What is the alternating current through the inductor if the frequency of the emf is 0.084 kHz? What is the alternating current if the frequency of the generator is changed to 1.09 kHz?
At 0.084 KHz: X 2pi*f*L 2 pi * 84 * 0.288 152 ohms At 1.09 KHz: X 2pi*f*L 2 pi * 1090 * 0.288 1972 ohms. I E/R At 0.084 KHz: I 0.1350/152 888 uA At 1.09 KHz: I 0.135/1972 68.5 uA
