Since capacitors in series all have the same current flowing through them, each capacitor will store the same amount of electrical charge, Q, on its plates regardless of its capacitance. This is due to the fact that the charge stored by a plate of any one capacitor must have come from the plate of its adjacent capacitor, as discussed in 1-3 below.
