Question

Two spherical conductors each of capacity C are charged to
potentials V and -V These are than connected by means of a fine
wire What is the loss of energy?Sir please answer this question

Hello,
The energy stored in the sphere with positive potential is,
(1/2)CV2
The energy stored in the sphere with negative potential is,
(1/2)C(-V)2 = (1/2)CV2
Total energy of the system before they are connected is =
(1/2)CV2 + (1/2)CV2 = CV2
When the spheres are connected all the charges on the spheres
are discharged because the spheres had equal and opposite charges
And the potential becomes zero
Hence, all the energy is lost That is, the energy lost is =
CV2
Hope this helps,
Keep posting and have a great day!
