In capacitor the electric charge stored in?

In a capacitor, the electric charge is stored in the electric field created between two conductive plates separated by an insulating material, or dielectric. When a voltage is applied across the plates, positive charge accumulates on one plate while an equal amount of negative charge accumulates on the opposite plate. This separation of charge creates an electric field that allows the capacitor to store energy, which can be released when the circuit is completed. The amount of charge stored is proportional to the voltage across the capacitor and its capacitance value.
