A Capacitor Of Capacitance “C”, Is First Connected To A Battery Of Voltage V And Fully Charged, Then It Is Connected To A Battery Of Voltage 2V.

Since in case of a parallel plate capacitor, the electric field is only between the plates, i.e., in a volume (a × d), the energy density =. This energy is localized on the charges or the plates but is distributed in the field. The energy stored in a capacitor with a capacitance, c, and an applied voltage, v is equivalent to the work done by a battery to move the charge q to the capacitor.

Therefore, The Total Energy Stored In The Capacitor When It Is Finally Charged To Q Coulombs Is.

If the capacitance of a conductor is c, c, it is uncharged initially and the potential difference between its plates is v v when connected to a battery. Alternatively, the amount of energy stored can also be defined in regards to the voltage across the capacitor.
