Three capacitors each of capacitance C = 2muF are connected with a battery of emf 30 V as shown in the figure . When the switch S is closed , the heat generated in the circuit will be

For the circuit shown in the figure, find the charge stored on capacitor in steady state.

Initially the 900muF capacitor is charged to 100 V and the 100muF capacitor is uncharged in the figure shown. Then the switch S_(2) is closed for a time t_(1) , after which it is opened and at the same instant switch S_(1) is closed for a time t_(2) and then opened. It is now found that the 100muF capacitor is charged to 300 V. If t_(1) and t_(2) minimum possible values of the time intervals, then findout (t_(1))/(t_(2))
