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.
