A battery of emf E is connected in series with a resistor, an inductor L. and a switch S. A capacitor C is connected in parallel to the inductor. When the switch is left in the closed position for a long time, the potential difference across the capacitor is zero. The switch is opened and the maximum potential difference across the capacitor is measured to be 140 V. Determine the capacitance of the capacitor if E = 60 V, R = 125 N, and L = 54.0 mH.
