A circuit is made from a capacitor and inductor only. The switch is initially open and the capacitor initially carries a charge Q0 = +10 microC on the top plate and -Q0 on the bottom plate. The capacitance is 1 mF and the indcutance is 4 mH. At t = 0 the switch is closed.
(a) What is the maximum current in the circuit?
(b) How long does it take to reach that current for the first time?
