Acircuit consists of a parallel-plate capacitor, an inductor, and a switch, which is initially open. the capacitor plates have an area of 1.00 × 10−4 m2 and are held 0.100 mm apart by a thin layer of barium titanate. the capacitor is charged to a potential difference of 14 v , and then the switch is closed. how much charge remains on the capacitor at the instant the energy stored in the inductor has increased to 80 % of its maximum?
