How can the energy of a capacitor be decresed by keeping the charge on the capacitor unchanged?

Where does the energy of a capacitor reside?

What is the net charge on a charged capacitor?

Calculate the energy stored in a capacitor?

The displacement current is produced across the gap between the two plates of a capacitor, when the charge on the capacitor

In a charged capacitor, the energy resides

A capacitor of capacitance 6muF is charged to a potential equal to 150 V. Itspotential falls to 90 V, when another capacitor is connected to it. Find the capacitance of the second capacitor and the amount of energy lost due to the connection.

Explain why the capacitance of capacitor increases when dielectri slab is inserted between the plates of the capacitor. Derive an expression for energy stored in a charged capacitor.

In what form is the energy stored in a charged capacitor?
