Update: Answers so far seem to indicate that I am asking ''where'' the charge would go if the circuit was closed again (after the battery was disconnected) - by means of completing the circuit with a piece of metal or even yourself. This is not what I am asking; I am asking where the charge would go if the circuit was left open (still with no …
When do capacitors "decide" to discharge?
More specifically, a capacitor discharges whenever the voltage in the circuit the capacitor is part of has a smaller magnitude than the voltage stored on the capacitor. So in the circuit above if the voltage across the capacitor is greater than the voltage of the voltage source, Vs, the capacitor will discharge through the resistor, R, …

Q. Two capacitors of 3 μ F and 6 μ F are connected in series and a potential difference of 900 V is applied across the combination. They are then disconnected and reconnected in parallel. The potential difference across the combination is
6.1.2: Capacitance and Capacitors
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 …

HVAC Start and Run Capacitor Explained and Replacement – …
After the motor starts up, the start capacitor and start winding are disconnected from the circuit, leaving the main winding to handle the load on its own. So why is a start capacitor needed, anyway? A start capacitor is required because a split-phase electric motor can not produce a rotating magnetic field on its own.
