In some cases it is useful to connect several capacitors in series in order to make a functional block: When this block is connected to a voltage source, each capacitor in the block stores an equal amount of charge, which means that the total amount of charge is evenly distributed across all of the capacitors, regardless of their capacitance.
There are both advantages and disadvantages to connecting capacitors in series together. On the plus side, the voltage rating of the series connection increases, allowing the circuit to handle higher voltage levels without risking damage to the capacitors. This feature is particularly useful in high-voltage capacitors in series applications.
In this case, by connecting five or more such capacitors in series, the high voltage would be divided across all the capacitors and the maximum rating would not be exceeded. Another example for the use of serially connected capacitors is a possible replacement of a car battery with a capacitor bank made of supercapacitors.
In series connections of capacitors, the sum is less than the parts. In fact, it is less than any individual. Note that it is sometimes possible, and more convenient, to solve an equation like the above by finding the least common denominator, which in this case (showing only whole-number calculations) is 40. Thus,
When this block is connected to a voltage source, each capacitor in the block stores an equal amount of charge, which means that the total amount of charge is evenly distributed across all of the capacitors, regardless of their capacitance. The amount of charge stored at each capacitor equals:
Every capacitor will 'see' the same voltage. They all must be rated for at least the voltage of your power supply. Conversely, you must not apply more voltage than the lowest voltage rating among the parallel capacitors. Capacitors connected in series will have a lower total capacitance than any single one in the circuit.
Capacitors
Example: Suppose you have two identical 1000uf capacitors, and connect them in series to double the voltage rating and halve the total capacitance. Let''s also assume they are rated for 100 wvdc (working voltage) and 125v maximum surge. Solve the equation, using V m = 125, and V b = 200.. Solution: R = (2x125 - 200) / (0.0015 x 1000 x 200) = 50/300 = 0.167 M = …

Connecting two identical capacitors in series, each with voltage threshold v and capacitance c, will result into a combined capacitance of 1/2 c and voltage threshold of 2 v.. However, it is far better to get a single capacitor that meets the higher voltage threshold on its own as combining capacitors in series will also lead to a higher Effective Series Resistance (ESR).

The Fundamentals of Capacitors in AC Circuits
Capacitors in Series. When two capacitors are placed in series, the effect is as if the distance between the outside plates were increased and the capacity is therefore decreased. On an alternating current supply, this effectively increases the opposition to a current flow in a similar fashion to that of resistors placed in series:

Capacitors in Series. When capacitors are placed in series, the total capacitance is reduced.Since current does not actually travel through capacitors, the total effect of capacitors in series is similar to separating the plates of the capacitor.
