A 63.9-µF capacitor is connected to a generator operating at a low frequency. The rms voltage of the generator is 3.60 V and is constant. A fuse in series with the capacitor has negligible resistance and will burn out when the rms current reaches 16.6 A. As the generator frequency is increased, at what frequency will the fuse burn out?
