1. The problem statement, all variables and given/known data By the time t = 0 network has been in steady state. At time t = 0, the switch S switches off. Determine the total amount of energy converted to heat in the circle of resistance to the establishment of a new steady state. 2. Relevant equations 3. The attempt at a solution Picture,attached. Okay before the switch is opened, both C and C2 are short circuited,so initial current i(0)=E/R. So I had this approach,okay let's find voltages on the capacitors vc(t) and from ic(t) = C* dv/dt , I will get a current and then it's easy to find the energy since it's integral of i*R^2 *dt (from 0 to infinity). I wrote down KCLs and KVLs,and used laplace transform,but things got really complicated,I think my approach isn't right(atleast not the shortest one). Are those laplace transforms that I wrote,even correct?
