Problem 5: A solenoid with self-inductance $L = 2$ H and carrying a steady current of 1 A has the current source suddenly turned off. What is the minimum capacitance that should be connected across the terminals of the solenoid in order to prevent the potential difference generated by collapse of the magnetic field from rising above 300 V?
