Three condesers of 6,10 and 15uf are connected in series across 200v supply.If the condensers are disconnected,how much energy can the condensers charged if they are connected in parallel?

Question

anonymous · Answer

im not sure , its my calculation
Energy = 1/2 CV^2
if parallel then 
Ce = C1 + C2 + C3

anonymous · Answer

is it 31uf is 31x10^-6 ? so (31x10^-6)(200v)/2 ?

anonymous · Answer

E =( 31x10^-6)(200)^2 / 2

anonymous · Answer

thats it?

anonymous · Answer

I think thats it but the first part if in series confusing me . Need a second opinion

Total capacitance for series connected capacitors is computed in a similar manner as resistors connected in parallel.  In other words the total capacitance is only 3 microfarad for the above arrangement.
