Physics - Capacitor Question with Solution | TestHub

The keys $S_1$ 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 $30\Omega$ resistor (between points P and Q ) will be 0.2 A (round off to 1st decimal place).

If key ${\mathrm{S}}_1$ is kept closed for long time such that capacitors are fully charged, the voltage difference between points P and Q will be 10 V .

At time $\mathrm{t}=0$, the key ${\mathrm{S}}_1$ is closed, the instantaneous current in the closed circuit will be 25 mA .

If key ${\mathrm{S}}_1$ is kept closed for long time such that capacitors are fully charged, the voltage across the capacitors ${\mathrm{C}}_1$ will be 4 V .
