A capacitor is connected across the terminals of an ac generator that has a frequency of 490 Hz and supplies a voltage of 39 V. When a
second capacitor is connected in parallel with the first one, the current from the generator increases by 0.18 A. Find the capacitance of
the second capacitor. Note: The ac current and voltage are rms values and power is an average value unless indicated otherwise.
