- Finally, the capacitors are in parallel and total charge distributes between them in direct ratio of capacity.
in steady state.
But this charge increases exponentially.
Hence, charge on at any time is
Initially, is uncharged so, whatever is the charge on , it is charge flown through switches.
2. Common potential in steady state when they finally come in parallel is
Total heat dissipated
