A capacitorCis fully charged with voltageV0. After disconnecting the voltage source, it is connected in parallel with another uncharged capacitor of capacitanceC2. The energy loss in the process after the charge is distributed between the two capacitors is :

Question diagram: A capacitor C is fully charged with voltage V 0 . After disc

Options:

Answer:
D
Solution:

Heat Loss is given by, 

H=C1C22C1+C2V1-V22

V1 is initial voltage of capacitor C=V0

V2 is the initial voltage of capacitor C2=0

=c×c22c+c2V0-02=C6V02

H=16C0V02
