    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

    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))
