Why is it that alternating current cannot be stored?
Batteries and capacitors are two examples of devices that store electrical energy. They do so by electrostatically or electrochemically, which entails polarizing a material or changing its chemical composition. Unlike capacitors, which store electrical current, batteries store electrical charge, which only exists when there is a moving electric charge.
Of course, there are gadgets that let you transform an AC current into a DC current, which can then be used to store energy and subsequently transform it back into an AC current.
A series of small pulses causes an oscillation that can store a lot of energy; all these systems do lose energy. Resistance in the wires will cause the oscillation to fade away once the source is removed. This is similar to the sound of a violin string after the performer lifts the bow from the string. The string will still produce sound for some time, but it will fade from hearing. Another dynamic way that AC can be stored is using capacitors and inductors.

Alternating current cannot be stored because it constantly changes direction, which makes it difficult to capture and store in a consistent form. Unlike direct current, which flows steadily in one direction, alternating current reverses direction at regular intervals. This characteristic makes it challenging to design storage devices capable of efficiently storing and retrieving alternating current energy.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
