A circuit has in series an electromotive force given by A circuit has in series an electromotive force given by E(t) = 5sin(91)t V  , a resister of 7 Ω  and inductor of 0.1H and a capacitor of  2x10^-4 farads. If the initial current is zero and the initial charge on the capacitor is 0.01 coulombs, find the charge at time t>0
