   Can anybody tell me which are the formulas to find energy in capacitors in series and in parallel?

   Lest us start with a single capacitor.
   
   What is the formula for its energy?

   The best way is to find the equivalent circuit and then use [itex]\frac{1}{2}[/itex]CV²

   If the capacitors are in series (resp. in parallel) then their charge (resp. voltage) is the same for each and so it would be better to use a formula having charge (resp. voltage).
