Homework Statement
A solenoid with self-inductance L=2H 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 mag field from rising above 300V.
Homework Equations
1/sqrt(LC) = resonance frequency
LD^2 + I/C = 0
The Attempt at a Solution
Are the capacitor and solenoid in series or parallel and I'm not sure exactly where to start.
Sorry that I don't have any work to show.
