Energy `'E'` is stored in a parallel plate capacitor `'C_(1)'`. An identical uncharged capacitor `'C_(2)'` is connected to it, kept in contact with it for a while and then disconnected, the enegry stored in `C_(2)` is.

Parallel Plate Capacitor |Energy Stored In A Charged Capacitor

Prove that energy stored in a parallel plate capacitor can be expressed by the relation (Q^2/2C) .

Answer the following: (a) Describe briefly the process of transferring charge between the two plates of a parallel plate capacitor when connected to a battery. Derive an expression for the energy stored in a capacitor. (b) A parallel plate capacitor is connected to a battery of potential difference V. It is disconnected from battery and then connected to another uncharged capacitor of the same capacitance. Calculate the ratio of the energy stored in the combination to the initial energy on the single capacitor.

A parallel plate capacitor is charged and then disconnected from the source. If the distance between its plates is doubled, explain how the following will change: Energy stored in the capacitor.

The ratio of energy stored in capacitors C_(1) and C_(2)

A capacitor is charge until it stores an energy of 1J. A second uncharged capacitor is connected to it, so that charge districutes equally. The final energy stored in the second capacitor is
