There is a capacitor voltage in the circuit
Reactance, Inductive and Capacitive | Physics
Although a capacitor is basically an open circuit, there is an rms current in a circuit with an AC voltage applied to a capacitor. This is because the voltage is continually reversing, charging and discharging the capacitor. If the frequency goes to zero (DC), X C tends to infinity, and the current is zero once the capacitor is charged. At very ...

How to Discharge a Capacitor
A capacitor is a component found in power circuits primarily used to store electrical energy. Stored electrical energy, measured in Farads, is then used by the circuit to achieve a high-voltage function when there isn''t any power supply. For instance, we commonly see this function of capacitors when a camera needs a flash to capture an image.
