An uncharged capacitor C, Resistances R_(1)=R and R_(2)=2R, cells of emf epsilon_(1)=epsilonand epsilon_(2)=epsilon are connected as shown in the figure. Switch S is initially connected to terminal 1 for a long time and then it is connected to terminal 2 for an another long duration. IF H_(1), U_(1) are the heat energies lost through the resistor R_(1) and energy stored in the capacitor respectively at steady state, when the switch is connected to terminal 1 and H_(2), U_(2) are corresponding value when the switch is connected to terminal 2. Choose the correct statements(s).

Answer»

`U_(1)//U_(2)=1`
`H_(1)//H_(2)=1//4`
work done by the cells during the TIME interval when they are active, is positive.
None of the above

Solution : From work ENERGY THEOREM
`W_("cell")=DeltaH+U_(f)-U_(i)`, where `U_(f)=U_(i)`
