Physics

Two capacitors C1 = 5.1 ?F, C2 = 19.8 ?Fare charged individually to V1 = 14.9 V, V2 =3.4 V. The two capacitors are then connected together in parallelwith the positive plates together and the negative platestogether.

Calculate the final potential difference across the plates ofthe capacitors once they are connected.

C) By how much (absolute value) is the total stored energyreduced when the two capacitors are connected?

Part a is 5.76V

Part b is 4.66E-5 C

Please help me with part c! In J please
