There is less charge on the two capacitors in series across a voltage source than if one of the capacitors is connected to the same voltage source. This can be shown by either considering charge on each capacitor due to the voltage on each capacitor, or by considering the charge on the equivalent series capacitance.

voltage, the capacitors draw an overcurrent due to harmonics that could seriously damage them, especially if there is a series or parallel resonance phenomenon occuring at a harmonic frequency. In order to protect capacitors against harmon-ics, the installation
If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse …
