In the circuit shown, initially there is no change on capacitors and keys `S_(1)andS_(2)` are open. The values of the capacitors are `C_(1)=10muF,C_(2)=30muFandC_(3)=C_(4)=80muF`.

Which of the statement (s) is/are correct?

Options

A. At time t = 0, the key `S_(1)` is closed, the instantaneous current in the closed circuit will be 25 mA.
B. If key `S_(1)` is kept closed for long time such that capacitors are fully charged, the voltage across the capacitor `C_(1)` will be 4 V.
C. The key `S_(1)` is kept closed for long time such that capacitors are fully charged, Now key `S_(2)` is closed, at this time, the instantaneous current across `30Omega` resistor (between points P and Q) will be 0.2 A (round off to `1^(st)` decimal place).
D. If key `S_(1)` is kept closed for long time such that capacitors are fully charged, the voltage difference between points P and Q will be 10 V.
