The total capacitance ( C T ) of the series connected capacitors is always less than the value of the smallest capacitor in the series connection. If two capacitors of 10 µF and 5 µF are connected in the series, then the value of total capacitance will be less than 5 µF. The connection circuit is shown in the following figure.
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.
This capacitive reactance produces a voltage drop across each capacitor, therefore the series connected capacitors act as a capacitive voltage divider network. The result is that the voltage divider formula applied to resistors can also be used to find the individual voltages for two capacitors in series. Then:
When n numbers of capacitors are connected in series, then their equivalent capacitance is given by, From these two expressions, it is clear that the mathematical expression of equivalent capacitance of capacitors in series is in the same form as the expression of resistance in parallel.
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.
Series connections produce a total capacitance that is less than that of any of the individual capacitors. We can find an expression for the total capacitance by considering the voltage across the individual capacitors shown in Figure 1. Solving C = Q V C = Q V for V gives V = Q C V = Q C.
