A 6-µF capacitor in series with a 2-? resistor is charged with a 9-V battery for a long time by closing the switch (position a in the figure). The capacitor is then discharged through an inductor (L = 35 mH) by closing the switch (position b) at t = 0.
(a) Determine the maximum current through the inductor.
(b) What is the first time at which the current is at its maximum?
