At time t = 0, terminal A in the circuit shown in the figure is connected to B by a key and an alternating current I(t)=I 0 cos(ωt), with I 0 =1A and ω=500rad/s starts flowing in it with the initial direction shown in the figure. At t= 6ω 7π , the key is switched from B to D. Now onwards only A and D are connected. A total charge Q flows from the battery to charge the capacitor fully. If C = 20 μF, R = 10 Ω and the battery is ideal with emf of 50 V, identify the correct statement(s).
