Combining capacitors in series reduces the total capacitance, and isn't very common, but what are some possible uses for it? It shouldn't be used to increase the voltage rating, for instance, since you can't guarantee that the middle will be at half the DC voltage of the total, without using bleeder resistors.
As for any capacitor, the capacitance of the combination is related to both charge and voltage: C = Q V. (8.3.1) (8.3.1) C = Q V. When this series combination is connected to a battery with voltage V, each of the capacitors acquires an identical charge Q.
However, when the series capacitor values are different, the larger value capacitor will charge itself to a lower voltage and the smaller value capacitor to a higher voltage, and in our second example above this was shown to be 3.84 and 8.16 volts respectively.
Connecting them in series increases the voltage capability (add voltage limits of all caps in series). To have robustness against short circuit specially ceramic capacitors that are connected to power lines. If capacitor shorts, it can burnt PCB trace or worst it may cause fire.
Thus, if you need to have a capacitor in a high voltage circuit it may be necessary, or just more convenient, to place them in series. Recovering the nominal capacitance of the individual capacitor, if needed, is a question of building up an array of them in parallel.
With series connected resistors, the sum of all the voltage drops across the series circuit will be equal to the applied voltage VS ( Kirchhoff’s Voltage Law ) and this is also true about capacitors in series. With series connected capacitors, the capacitive reactance of the capacitor acts as an impedance due to the frequency of the supply.
