Capacitors in Series:

Capacitors in series are combined like resistors in parallel. The total capacitance, C_T, of capacitors connected in series Figure, is shown in Equation (3-9).

Figure: Capacitors Connected in Series

1/C_T  =1/C₁ +1/C₂ +1/C₃+...1/C_N                                                     (3-9)

While only two capacitors are in series in the Equation (3-9) might be simplified as provide in Equation (3-10).  As display in Equation (3-10), this is valid whenever there are only two capacitors in series.

C_T = C₁ C₂/ C₁+C₂

While all the capacitors in series are the similar value, the total capacitance could be found through dividing the capacitor's value through the number of capacitors in series as provided in Equation (3-11).

C_T = C/ N

where

C = value of any capacitor in series

N = denotes number of capacitors in series along with the similar value.
