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

What is the formula for its energy?

The best way is to find the equivalent circuit and then use $\frac{1}{2}$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).
