The energy stored in a capacitor is given by
where C is the value of the capacitance while V is the voltage difference applied to the capacitor.
Let's calculate the energy of the first capacitor:
And now the energy of the second capacitor:
So, the total energy stored in the two capacitors is
where C is the value of the capacitance while V is the voltage difference applied to the capacitor.
