CAPACITANCEDC CircuitsWhen 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.C_{T} = (3-10)C_{1}C_{2}C_{1}C_{2}When all the capacitors in series are the same value, the total capacitance can be found bydividing the capacitor’s value by the number of capacitors in series as given in Equation (3-11).C_{T} = (3-11)CNwhereC = value of any capacitor in seriesN = the number of capacitors in series with the same value.Capacitors in parallel are combined like resistors in series. When capacitors are connected inparallel (Figure 14), the total capacitance, C_{T}, is the sum of the individual capacitances as givenin Equation (3-12).C_{T} = C_{1} + C_{2} + C_{3} + ... + C_{N}(3-12)Figure 14 Capacitors Connected in ParallelES-03 Page 14 Rev. 0
