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.

Why capacitor used in a DC inverter?
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
What is the main function of a capacitor?
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.
Do ac capacitor have polarity?
no
What is the function of Thyristor module in inverters?
Usually these devices will conduct during an AC phase cycles to charge a capacitor to produce DC.
What is ac ground?
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
Why a capacitor does not accept AC?
A capacitor conducts AC but do not conduct DC because it is meant to store charge.
How do you use a diode to charge your saltwater capacitors with ac voltage?
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.
Why capacitor does not store alternate current but store direct current?
A capacitor can store both alternating current (AC) and direct current (DC). However, in an AC circuit, a capacitor blocks the flow of steady-state current because it takes time to charge and discharge, causing a phase shift in the current. In contrast, in a DC circuit, a capacitor can store charge and act as a temporary energy storage device.
How does capacitor discharge while ac supply is on?
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.
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)
Why won't a capacitor conduct DC?
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.
Can ac supply charge capacitor?
A: Absolutely charges and discharges the net result is zero
What is the role of a capacitor in an AC compressor system?
A capacitor in an AC compressor system helps to store and release electrical energy to help start the compressor motor and keep it running smoothly.
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.
How do you safely discharge an AC capacitor?
To safely discharge an AC capacitor, first turn off the power supply to the capacitor. Then, use an insulated screwdriver to short the terminals of the capacitor together to release any stored electrical charge. Be cautious and ensure you are wearing appropriate safety gear to prevent electric shock.

What is the function of the ac condenser capacitor in an air conditioning system?
The function of the AC condenser capacitor in an air conditioning system is to store and release electrical energy to help start the compressor and keep it running smoothly.
