Then charge stops moving. Recall that we defined the capacitance of a capacitor to be the ratio (frac{q}{V}) of the charge on the capacitor to the corresponding voltage across the capacitor. (frac{q}{V}) for our two-terminal combination circuit element is thus the equivalent capacitance of the two terminal circuit element.
Why is charge the same on every capacitor in series?
In the normal case, this means that if charge flows out one lead it must flow into the lead of another capacitor (the voltage source obeys KCL) so all the capacitors must have equal charge. In the non-ideal case, of course, this does not apply. Two capacitors in series can be considered as 3 plates.

Capacitance is charge per voltage. Two equal-valued capacitors in series containing the same charge will have the same charge available at the two outer capacitor plates as a single capacitor does, but the voltage will be double. So the capacitance is half.
Why is the charge everywhere the same in a series of Capacitors …
Capacitors in Series have the same current flowing through them: Total Current = I¹ = I² = I³ = etc. . Therefore each capacitor will store the same amount of electrical charge on it''s plates regardless of it''s capacitance.. This happens because the charge stored by a plate of any one capacitor must have come from the plate of its adjacent capacitor.
Increase capacitor voltage rating by using multiple capacitors?
$begingroup$ @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 …

Why voltage is not the same for the capacitors in series?
Each capacitor has an equal amount of positive and negative electric charge so each capacitor is electrically neutral. That means the electric field between the capacitors has to be zero. Since the electric field between two points is the gradient (rate of change) of potential between the points, the potential difference between the right plate ...
