A capacitor of capacitance C is charged ...

A capacitor of capacitance C is charged fully by connecting it to a battery of emf B. It is then disconnected from the battery. If the separation between the plates of the capacitor is now doubled, how will the following change ?
Energy stored by the capacitor.

Text Solution

Verified by Experts

The energy stored in the capacitor is, `U = (Q^2)/(2C)`
Now, when the distance between the plates is doubled, the capacitane becomes half. Hence, the energy stored will also double.
