The capacitance of a charged capacitor is C and the energy stored in it is U. What is the value of charge on the capacitor?

The energy of a charged capacitor is stored

In a charged capacitor, the energy is stored in

In a charged capacitors energy is stored

If the charge on a capacitor is increased by 2C, then the energy stored in it increases by 21 %. The original charge on the capacitor is

A capacitor of capacitance of 10 mu F is charged to 10 V . The energy stored in it is

A capacitor is charged using a a battery and energy stored is U. After disconnecting the battery another uncharged capacitor of same capacitance is connected in parallel to the first capacitor. Then loss of energy is equal to
