SUMMARY

The discussion centers on the behavior of capacitors in circuits when a battery is removed. It is established that when capacitors are in series, they do not approach the same final electric potential due to differing capacitances. In contrast, when capacitors are in parallel, they will equalize their electric potential after the battery is removed, regardless of their individual capacitances. This distinction is crucial for understanding capacitor behavior in various configurations.

PREREQUISITES
  • Understanding of capacitor circuits
  • Knowledge of electric potential and capacitance

For a circuit of capacitors...can it be generalized that when the battery is removed, each capacitor approaches the same final electric potential, regardless of whether the capacitors were in series or parallel?

no. consider a circuit with 2 unequal capacitors in series with a battery.
 
I see, I see...so that's what it comes down to...what happens if the capacitors were originally in parallel to each other and the battery was then removed; the electric potential difference afterwards for each one should still be equal to each other regardless of the capacitance, right?
