19.6 Capacitors in Series and Parallel – College Physics
Capacitors in Parallel Figure 2(a) shows a parallel connection of three capacitors with a voltage applied.Here the total capacitance is easier to find than in the series case. To find the equivalent total capacitance, we first note that the voltage across each capacitor is, the same as that of the source, since they are connected directly to it through a conductor.
