In some cases it is indeed a way of storing energy, similar to the battery. It however allows for higher transfer of this energy, although a rather
[SOLVED]
The dielectric of a capacitor does not store energy. The energy is stored in the electric field that occupies the same volume as the dielectric. The dielectric allows the electric field between the plates to have a higher flux density so as to increase its energy capacity.

6 FAQs about [The capacitor in the circuit does not store energy]
Does a capacitor store energy on a plate?
A: Capacitors do store charge on their plates, but the net charge is zero, as the positive and negative charges on the plates are equal and opposite. The energy stored in a capacitor is due to the electric field created by the separation of these charges. Q: Why is energy stored in a capacitor half?
What is the principle behind a capacitor?
A: The principle behind capacitors is the storage of energy in an electric field created by the separation of charges on two conductive plates. When a voltage is applied across the plates, positive and negative charges accumulate on the plates, creating an electric field between them and storing energy.
Why does a capacitor have no charge?
it stores energy in the form of being charged. therefore, no charge is stored, the dielectric material is biased by the externally applied inductor electric field and the energy stored in the electric field of the capacitor is due to this bias. Why capacitor is not fully charged?
Do capacitors store charge?
Capacitors do not store charge. Capacitors actually store an imbalance of charge. If one plate of a capacitor has 1 coulomb of charge stored on it, the other plate will have −1 coulomb, making the total charge (added up across both plates) zero.
How energy is stored in a capacitor and inductor?
A: Energy is stored in a capacitor when an electric field is created between its plates. This occurs when a voltage is applied across the capacitor, causing charges to accumulate on the plates. The energy is released when the electric field collapses and the charges dissipate. Q: How energy is stored in capacitor and inductor?
Can a capacitor be used to store energy?
Since there is an electric field inside the capacitor, there is also energy stored in the capacitor (you can use the energy density of the electric field). So obviously, a capacitor can be used to store energy. Here is the charge on a capacitor as a function of time after being hooked to a DC battery. Hope that helps.
