$begingroup$ Correct me if I am wrong, but how does the capacitor pass current when it is in series with an AC signal source? The current "passes" but not in the way that you expect. Since the voltage changes sinusoidally, the voltages also changes across the capacitor, which gives rise to an EMF that induces a current on the other …
When 2 capacitors are connected in parallel, the voltage rating will be the lower of the 2 values. e.g. a 10 V and a 16 V rated capacitor in parallel will have a maximum voltage rating of 10 Volts, as the voltage is the same across both capacitors, and you must not exceed the rating of either capacitors.
When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitors'' capacitances. If two or more capacitors are connected in parallel, the overall effect is that of a single equivalent …

$begingroup$ @Majenko: The point is to reduce the high frequencies enough so that the active circuit in a voltage regulator can handle the remaining ones. Usually up to a few 10s of kHz is OK. For example, I often use some 950nH 600mOhm 200mA 0805 ferrites. With 22uF capacitance following these, you get one pole at 12 kHz from the R-C action, and …
