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 (omega t)`, with `I_(0) = 1 A and (omega) = 500 rads^(-1)` starts flowing in it with the initial direction shown in the figure. At `t = (7pi//6omega)`, 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(mu)F, R = 10(Omega) and the battery is ideal with emf of 50 V, identify the correct statement(s).
.

Options

A. Magnitude of the maximum charge on the capacitor before ` t=(7pi)/( 6 omega) is 1 xx 10 ^(-3) C .`
B. The current in the left part of the circuit just before ` t= ( 7pi)/( 6omega ) ` is clockwise
C. Immediately after A is connected to D , The current in R is 10 A.
D. ` Q= 2 xx 10 ^(-3) C `

Answer

C, D
