A capacitor is a device which blocks DC, but allows AC. When a capacitor is completely charged it does not allow current to pass through it. Initially when capacitor starts charging it has maximum current which flows and voltage is minimum, during charging current decreases with time and voltage increases. When capacitor is completely charged, it has maximum voltage and minimum current.
However the AC has both positive and negative half cycles, during positive half cycle capacitor starts charging but during negative half cycle it discharges, and hence it doesn't get fully charged at AC, and current always flows through it.

What device creates a potential difference in an electric circuit?
A battery is the device that creates a potential difference in an electric circuit. It establishes an electric field within the circuit that allows charges to move from the positive terminal to the negative terminal, creating an electrical current.
