Homework Statement
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.
Homework Equations
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?
