 Prove that-
"The ratio of change in potentials of conductors after connecting two charged conductors is inversely proportional to their capacitances".

Energy stored in a capacitor : A capacitor is a device to store energy. The process of charging up a capacitor involves the transferring of electric charges from its one plate to another.The work done in charging the capacitor is stored as its electrical potential energy.  Consider two insulated conductor A and B of capacitance and carrying charges and .  Let and be their respective potentials.
If connect with wire charge flow higher to lower potential
