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.
capacitor is component used to store and release the electric charge.and also it has feature to block the dc but bypass ac.and inverter is device which converts ac to dc and then again ac
They pass AC and block DC. So they are used in filters of various types as well as signal coupling. The capacitor is use to store the electric energy in the automobile ignition system. The capacitor is attached to the secondary winding of ignition coil. When contact breaker breaks the contact to the primary winding and sudden collapse of magnetic flux induces the high voltage to the secondary winding. This excess voltage is stored in capacitor. Capacitor releases the electric energy when it need. It protects cam and contact breaker points from corrosion or rusting.
Usually these devices will conduct during an AC phase cycles to charge a capacitor to produce DC.
no
If a circuit is grounded through a capacitor it is referred to as AC ground because ac signal can pass through the capacitor DC level is blocked
A capacitor conducts AC but do not conduct DC because it is meant to store charge.
Simply include the diode in one of the AC supply lines to your capacitor. (not sure what a salt water capacitor is) but, all capacitors only store charge, which is discharged as a DC current.
For part of the AC voltage wave, the capacitor will be above the source voltage, and will discharge until the AC voltage wave increases above the capacitor's stored voltage.
capacitor blocks DC, after it finishes charging. Actually, it resists any CHANGE to DC (ie ac), after it has finished charging. IRT the actual question, current will always flow, as long as there is a closed circuit.
A: Absolutely charges and discharges the net result is zero
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.
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.
Sure, but it won't mean anything unless the Thevenin source is an AC source. In that case, simply determine the frequency of the source, and draw the appropriate reactance in the circuit where the capacitor belongs. If the Thevenin source is DC, then the frequency is zero, the reactance of the capacitor is infinite, and you can show it as an open circuit, i.e. not there.

Capacitors store electrical charge. Imagine we have a capacitor. At time 0 seconds we connect a DC voltage across the capacitor - immediately as the voltage is connected the capacitor is at 0 volts and the maximum current (relative to the circuit resistance) flows. At this extreme the capacitor can be treated as a short circuit, so for high frequency AC volts we should treat a capacitor as being a short circuit. As time passes the current in the circuit will go down and the voltage of the capacitor will go up - this is because as the capacitor gains more charge it gains more voltage, lowering the voltage across any resistance in the circuit consequently lowering the current in the circuit. When the capacitor is virtually full no current will flow at all and the voltage across the capacitor will equal the DC source voltage. At this extreme the capacitor can be treated as an open circuit, so for low frequency AC (allowing the capacitor to fill up before the current alternates) we can treat the capacitor as being an open circuit. Technically, it is not an open/closed circuit when it comes to AC because the capacitance will results in a signal lag or lead. However, if the frequency is low/high enough the lag/lead is often negligable.
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
