Why capacitor does not store alternate current but store direct current?

Because Alternet current has both positive as well as negative cycle capacitor does not conduct for negative cycle of the Alternet current and DC all are positive cycle thats why it capacitor conduct for DC not for AC

What is an electrical capacitor?
Electricity is either alternating current or direct current, abbreviated AC or DC. An AC/DC Capacitor can be used in either an AC or DC current.
Which type of current capacitor can block and which type of current capacitor can store?
In an electronic circuit a capacitor can be used to block direct current. In general a capacitor stores electric charge. The charge in a capacitor is the voltage times the capacitance and that is also equal to the charging current times the time (all quantities in SI units - seconds, volts, amps, coulombs, farads)
What is used to store potential electrical energy?
A Battery or a capacitor.
What devices do you use to store electricity?
capacitor inductor battery
What are the current promotions offered by Direct Lighting?
There are many discounts, promotions, coupons, and vouchers for Lighting Direct. (My search did not find Direct Lighting, but Lighting Direct.) It depends on the site that and the store that you go to. Dollars and percents off and by some get some free.

Can resistors stores current?
No, a resistor cannot store current. A capacitor is a passive device that can store a small amount of DC current.
If the capacitor store the charge from the magnetic field then the capacitor is called?
it wouldn't store a charge from the magnetic field, only the current induced on the circuit would be stored
Can a capacitor store power continuously?
Yes, but not for ever. A capacitor can never be perfectly insulated and it has a small leakage current, that causes it to discharge eventually.
Does a capacitor store energy in form of an magnetic field?
Current stops going into a capacitor when it's voltage is equal to the supply voltage. From then there is no flow of current, so there is no magnetic field. Yet the capacitor remains charged and has energy to release if required.
Why dc can be stored ac cannot stored?
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 does a power supply capacitor hold?
when the current supply to the capcitor it can store or hold little amount of charge
Can capacitor store charge from ac source?
Yes. A capacitor stores charge from any source, including AC.The difference between DC and AC, however, is that the capacitor will be constantly changing in charge, in step with the AC. Due to the nature of the capacitor, the current through the capacitor will lead the voltage by some amount, depending on capacitance and resistance. {In the ideal case of a perfect capacitor, conductors, and AC power source, the current will lead the voltage by 90 degrees phase angle.}This is called capacitive reactance.Another way for a capacitor to store charge from an AC source, of course, is to place a rectifier diode in front of the capacitor. This, then, becomes an AC to DC converter.
How a capacitor store charge?
by using capacitor plates. The length,area ,thickness and type of the plate determines the amount of charge a capacitor can store.
What happens when dielectric is a conductor?
Yes possible. As a capacitor even with air as dielectric allows alternating current to pass through the capacitor filled with some material as dielectric would allow current to pass through it
Is batteries alternative current or directly current?
Batteries store DC, or Direct Current. The correct term for AC is Alternating Current.
