In the circuit shown,initially there is no charge on capacitors and keys $$S_1 and S_2$$ are open. The values of the capacitors are $$C_1 = 10 \mu F, C_2 = 30 \mu F and C_3 = C_4 = 80 \mu F.$$

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

At time t = 0, the key $$S_1$$ is closed, the instantaneous current in the closed circuit will be 25 mA.

Ifkey $$S_1$$ is kept closed for long time such that capacitors are fully charged, the voltage across the capacitor $$C_1$$ will be 4 V.

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 $$30 Ω$$ resistor (between points P and Q) will be 0.2 A (round off to $$1^{st}$$ decimal place).

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.
