## 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.Β  Consider two insulated conductor A and B of capacitance and carrying charges and .Β  Let and be their respective potentials. and If connect with wire charge flow higher to lower potentialΒ Total charge on system Total capacitance Electric field distance curve by uniformly charged non- conducting sphere.E outside inside
