What is the difference between the capacitance of a capacitor when they are connected in by a battery and disconnect from the battery
A capacitor of capacitance C is charged fully using a battery of e.m.f, E . It is then disconnected form the battery . If the separation between the plates of the capacitor is now doubled. What will happen to : Charge stored by the capacitor,P.D across it, field strength between the plates and energy stored between the plates of the capacitor.. Answer the question again, if the battery is kept connected
