A capacitor is connected to an ac generator that has a frequency of 3.4 kHz and produces a rms voltage of 1.9 V. The rms current in the capacitor is 26 mA. When the same capacitor is connected to a second ac generator that has a frequency of 4.6 kHz, the rms current in the capacitor is 78 mA. What rms voltage does the second generator produce?
