The energy stored on a charged capacitor is 0.5*Q*V or 0.5*C*V2
BUT
what is the electrical work done by the supply as it transfers the charge to the capacitor?
I have heard two answers:
W=QV and W=0.5*QV
the first answer implies, i think, that energy is required to move charges against the already present charges on the capacitor plate. is this correct?
