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.
When capacitors are connected in series, the capacitor plates that are closest to the voltage source terminals are charged directly. The capacitor plates in between are only charged by the outer plates. In a series circuit, the total voltage drop equals the applied voltage, and the current through every element is the same.
Why it’s important: Capacitors in series reduce the overall capacitance of the system. This can be used to engineer a specific capacitance using commonly manufactured components. Capacitance is the ratio of the total charge stored in the capacitor to the voltage drop across it:
Figure 8.3.1 8.3. 1: (a) Three capacitors are connected in series. The magnitude of the charge on each plate is Q. (b) The network of capacitors in (a) is equivalent to one capacitor that has a smaller capacitance than any of the individual capacitances in (a), and the charge on its plates is Q.
The electrons that get accumulated on the top plate of the second capacitors in series has an electric field which effects the amount of charges that get deposited on the first plate. The result is less charges and hence not the complete use of the capacitors space. Thus we can say that capacitance has decreased.

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.
Then we can see that if and only if the two series connected capacitors are the same and equal, then the total capacitance, CT will be exactly equal to one half of the capacitance value, that is: C/2.

With series connected capacitors, the capacitive reactance of the capacitor acts as an impedance due to the frequency of the supply. This capacitive reactance produces a voltage drop across each capacitor, therefore the series connected capacitors act as …

Why is there no current flow in a series capacitor circuit? In a series capacitor circuit, the capacitors are connected in a line, which means the same amount of charge must pass through each capacitor.

There are two simple and common types of connections, called series and parallel, for which we can easily calculate the total capacitance. Certain more complicated connections can also be related to combinations of series and parallel.
With capacitors in series, the corresponding terminals of all of the capacitors are no longer connected together. Rather, the terminals are connected in succession, one right after the other, in a chain as shown above. The net effect is that all …
As far as charges entering and leaving the voltage source are concerned, one thing is certain; no electron that leaves that source can ever return to it "in person" because there are dielectric barriers in the capacitors, which the electrons cannot traverse.
When capacitors are connected in series, their individual capacitance values contribute to the total equivalent capacitance. The series connection is achieved when the positive plate of one capacitor is connected to the negative plate of the subsequent capacitor. This forms a continuous path for current flow, creating a series circuit.
What happens if there is no Capacitor in a 1-Φ Motor? A capacitor start motor will not run without a rated capacitor connected in series with the starting winding because the capacitor is needed to create the necessary phase shift to start the motor. The capacitor plays a crucial role in single-phase motors by creating a phase shift in the ...

It is equivalent to the diagram to the bottom right. If two or more capacitors are connected in series, the overall effect is that of a single (equivalent) capacitor having the sum total of the plate spacings of the individual capacitors. Thus for series capacitors the equivalent capacitor is less than the individual capacitors.
