Capacitors are used in ac machines to assist the field during starting.
A capacitor is a capacitor, no matter what circuits you use it in. There is no difference between one used in AC and one in DC, except perhaps the size that is appropriate.

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
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.
If you mean run capacitor, as in the run capacitor for an AC motor, it is usually a round or oval cylinder.

To test a capacitor on an AC unit, you can use a multimeter set to the capacitance setting. Disconnect the capacitor from the unit, discharge it, and then place the multimeter leads on the capacitor terminals. The reading should match the capacitance rating on the capacitor. If the reading is significantly lower, the capacitor may be faulty and in need of replacement.
To test an AC capacitor, you can use a multimeter set to the capacitance setting. Disconnect the capacitor from the circuit, discharge it, and then connect the multimeter leads to the capacitor terminals. The reading should be close to the labeled capacitance value. If the reading is significantly lower or higher, the capacitor may be faulty.
A capacitor conducts AC but do not conduct DC because it is meant to store charge.
no
To check a capacitor on an AC unit, you can use a multimeter set to the capacitance setting. First, make sure the power to the unit is turned off. Then, discharge the capacitor by using an insulated screwdriver to bridge the terminals. Next, remove the capacitor and use the multimeter to measure the capacitance. If the reading is significantly lower than the labeled capacitance, the capacitor may be faulty and in need of replacement.
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.
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.
capacitor acts as a small battery ,during rectification ac to dc it gets some blank space (no current) to fill this current from capacitor is used.
