However, in real life, capacitors in general and electrolytic capacitors in particular behave badly when placed in series. If you have all of your capacitors in series fully charged, and shorted the output (top capacitor) to ground, mismatches in the capacitor values will result in voltages with respect to ground between individual electrolytic
