Two 20 microfarad capacitors are wired in parallel with each other in series with a single 5 ohm resistor. The previously described circuit branch is in parallell with a circuit branch with a 5 milliHenry inductor and 10 ohm resistor in series. A six volt battery powers the circuit.
A. When the capacitor has half of its final charge, what is the current through the inductor?
B. What is the maximum energy stored in the capacitor?
