CAPACITANCE
DC Circuits
When only two capacitors are in series, Equation (3-9) may be simplified as given in Equation
(3-10). As shown in Equation (3-10), this is valid when there are only two capacitors in series.

When all the capacitors in series are the same value, the total capacitance can be found by
dividing the capacitor’s value by the number of capacitors in series as given in Equation (3-11).
CT =
(3-11)
C
N
where
C = value of any capacitor in series
N = the number of capacitors in series with the same value.
Capacitors in parallel are combined like resistors in series. When capacitors are connected in
parallel (Figure 14), the total capacitance, CT, is the sum of the individual capacitances as given
in Equation (3-12).
CT = C1 + C2 + C3 + ... + CN
