1. The problem statement, all variables and given/known data Long time after closing K1,k2 and k3 the energy stored in each capacitor is? 3. The attempt at a solution My method is to find out an expression for the current through the capacitor (of net capacitance 2C) at any time t and use I = CdV/dt to find out V across it at t=inf. However this method appears to be very long. Is there any shortcut?
Also notice: that will leave you with a fairly simple circuit. The capacitors in combination with R_{3} are in parallel with R_{2[/SUB, but the voltage drop across R3 is zero since there is no current through it.}
No. As t → ∞ : The only current flowing is through R_{1} and R_{2}. What is the voltage drop across R_{2}?
