Your question should read, "Can electrical energy be stored?", as 'power' is simply the rate of utilising energy. The answer is, in a sense, yes. Hydroelectric generation systems 'store' huge amounts of energy in reservoirs, which can then be converted into electrical energy upon demand. Some hydroelectric plants will actually pump water from a lower reservoir to an upper reservoir during periods of low demand so that the upper reservoir is refilled, ready to provide more energy on demand. Direct storage of very small amounts of energy can be achieved with capacitors, but the amount of energy stored is very low and not of much use other than for specific, low-energy, applications -certainly not enough for practical purposes. Finally, we could argue that batteries store electrical energy although, like hydroelectric dams, the energy is provided by the work done (in this case, by chemical reaction) by the battery rather than by 'storage'.
Using a 12 volt battery, 12 volts can be stored. If you have TWO 12 volt batteries in series, you can store 24 volts. It depends on how much storage you have.
I suspect you're referring to storing power (voltage * current), not necessarily voltage. Power can be stored as electrical power in batteries and capacitors, or as kinetic power (such as in a flywheel or generator rotor), and even as potential energy (such as in a water tower), or chemical energy (like you body stores energy as fat, or creating hydrogen from water using electrolysis). You can store as much as you have physical material (there's only so much water to put in a water tower) and money to build the necessary equipment. Different methods will store more energy than others, but will have more losses associated with that storage, or may have bleedoff problems where the power stored will decay at an accelerated rate (so many percent per hour, or day).
Alternating Current is measured in Amperes.
The symbol for alternating current is: ~
Alternating current is normally produced by rotating the magnet in the coil of an induced alternating voltage. When connected to a circuit, an alternating current will flow.
It stands for volts alternating current.
The introduction of alternating electrical current, in 1920, eliminated the need for a return wire. Alternating current, AC, replaced direct current, DC.
An AC current can not be stored.
b'coz ac changes continiously with time
"Current" cannot be stored at all in any way; when you stop it moving, it isn't current any more and moving it means using it. The energy carried however, can be stored in several different ways.
AC, or alternating current.AC, or alternating current.AC, or alternating current.AC, or alternating current.

Why direct current (DC) can be stored but alternating current(AC) can not be? Current means flow of charge per unit second. Any flow cannot be made stationary. Then it is not flow. Hence both direct current and alternating current cannot be stored. We can store only charges. In capacitors we store charges and not current. For storing we use direct supply or direct voltage When a capacitor is connected to a battery, which is a source of direct voltage, each plate of the condenser get charged. Charges remain in the plates. No current flows in between the plates. When the source is removed, there are some charges left in the plates. We say that charges are stored in the plates. If an alternating source of supply is connected in between the plates,every instant ,the charges in the plates are alternating and they are not stationary. When ac supply is removed, all the charges move out of the plates and hence no charge is left in them. Hence charges can be stored with dc supply and not with ac supply. However as long as the ac is connected to the capacitor, the capacitor gets stored and emptied with the frequency of the ac supply.
Alternating current. Direct current is used in batteries.
Alternating current is better than direct current for transmission.
Nicola Tesla is the father of alternating current.
