If a capacitor is connected to an AC source, it would ordinarily charge and discharge with every cycle of the source and not cause the kw-hr meter to rotate. If the capacitor is charged through a rectifier the kw-hr meter would move if the amount of transferred energy (plus losses) is enough to be significant in terms of the kw-hr meter measuring capability.

you ought to use a capacitor it quite is stamped 230VAC or extra beneficial. Capacitors designed for the mains are constantly non-electrolytic and are measured in AC volts. this is because of the fact mains voltages can spike over 350VDC.

It will rotate the amount equivalent to the energy consumed to charge the capacitor.

Yes. the amount of movement depends on the amount of power drawn to charge it. If the source is AC there will be a constant AC current through the impedance of the capacitive circuit. Without a series resistance it will blow the fuses.

theoretical the KWH meter will not rotate because the power factor PF = 1 for capacitive reactive load

If you are charging a capacitor from a d.c. source it will absorb energy as per E=1/2 C*V^2. You can then use this as a power source if you are so inclined.

Theoretically it should not rotate but as there are losses,it will move
