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.
What else can I help you with?
What type of electrical equipment cannot convert AC into DC?
A transformer cannot convert AC into DC.
What is difference between advantage and disadvantage AC and DC power transmission line?
The main advantage of ac- it required less maintainance The main disadvantage of ac-it can not be stored the main advantage of dc -it required less amount of conductors to transmit and easily stored The main disadvantage of dc-it is more dangerous than ac at high voltage
Can you use an AC contactor in the place of DC contactor?
No, you definitely cannot.
Does electrical transformer use a DC or AC source?
A transformer is a device to convert high voltage AC to low voltage AC & vice-versa. It works on the principle of induction. Since induction occurs only in an AC supply, a transformer cannot work on DC.. So, it is not possible to convert DC supply to AC using transformer. You would need an inverter to convert DC to AC.
Can AC motor work on DC?
use a inverter to change dc to ac or couple it to a ac motor making it a motor generator. Comment: AC motors cannot run on DC since their principle of operation based on induction. There's an exception,however, and thats for Universal Series motor which can run on either AC or DC.

Can we charge a phone with dc current?
Your mobile phone charger already have ac to dc converter , as ac supply can't stored. and you can charge directly with dc supply by maintaing volage of battery and dc source.
What is another name for rectifier convert dc to radio waves ac?
You cannot use a rectifier to go from DC to AC. You need an oscillator.
What is the procedure of storing the ac current?
AC current cannot be stored, it must be used as it is generated.
Can you use an AC contactor in the place of DC contactor?
No, you definitely cannot.

How you can store electric current which is produced from ac generator?
First ac has to be rectified into dc and then that could be stored in a secondary cell in the form of chemical energy.

What is alternate current and direct current difference between?
Alternating Current (AC) is the type of electricity typically used in households. With AC, the magnitude and direction of electricity vary. Direct current (DC) is a source of electricity that does not vary in direction. An example of a DC source is a battery, or solar cells. The main difference between the two types of currents is simply the direction, as made quite clear by the names: AC = varied direction and magnitude where as DC = continuous current. Alternate current cannot stored but direct current can be stored examples in case of battery cells
Ac to DC formula?
formula for ac to dc
Is there any possibilty of ac and DC flows in conductor at a time and get DC and AC with two reference AC and DC?
A typical AC waveform is symmetrical about a zero crossing point. You can bias the AC with DC such that the AC waveform is symmetrical about the DC voltage.
