A magnetic core’s high permeability, on the other hand, allows it to concentrate the field in a predefined region of space. This lets us increase the magnetic coupling between windings. In this way, using a magnetic core enables the creation of inductors with large inductances and transformers with high coupling.
The capacitor stores electrical energy in its electric field. The amount of stored energy is directly proportional to the applied voltage and the capacitance of the capacitor, which is a measure of its ability to store charge. The dielectric between the plates is quite important.
An electric field is produced when voltage is placed across a capacitor's plates, and energy is stored in this field as a result of the separation of charges on the plates. The energy is released when the capacitor discharges, allowing the stored charge to flow through a circuit.
A capacitor, on the other hand, uses an electric field to store energy. An electric field is produced when voltage is placed across a capacitor's plates, and energy is stored in this field as a result of the separation of charges on the plates.
What is a capacitor? Capacitors are devices which store electrical energy in the form of an electric field. The process is quite similar to the way mechanical springs store energy in the form of elastic material deformation, to the extent that the math describing both is quite similar, save for the variables used.
The objective of this resource is to offer the reader a guide to capacitor technology in an easy-to-swallow capsule with a (hopefully) non-drowsy formula. What is a capacitor? Capacitors are devices which store electrical energy in the form of an electric field.

Capacitors/inductors have memory?
When a capacitor or inductor has memory, it means that it can store and retain an electrical charge or magnetic energy even after the power source has been removed. This is due to the inherent properties of the components, such as the dielectric in a capacitor or the magnetic core in an inductor.

How big do the capacitors have to be?
I have to agree with Bakmeel. It is not a matter of energy storage, is has to do with the magnetic alinement of the metal particles in the iron at the moment the ac is cut. If you later reconnect in a way that would require a different magnetization direction, there is almost a zero impedance while the magnetic direction is flipped. Jan Didden

Controlling and Preventing Core Saturation in Inductors
In saturation, however, the magnetic flux is almost constant. As a result, no voltage is induced across an inductor when its core saturates. Instead, the inductor behaves almost like a short circuit. Saturation Limits the Maximum Magnetic Field Force. To avoid saturation, we need to limit the magnetic flux density (B) to below B sat.
