Any Physicists or Electricians here?

I didn't understand your question. But, as an active element a capacitor can stored a fixed amount of energy and once this energy is depleted the energy will remain zero on the capacitor until it is 'refiled'. How will get 'refilled' or how the capacitor operate under certain conditions will depend of the other circuit elements that interact with said capacitor(s). That is the circuit network configuration.
