As the charge in the external capacitor increases, so does the voltage across it. This voltage is also one input of a comparator. When the input of the comparator reaches the threshold voltage, a discharge circuit (resistor to ground) is connected and charge is ...
When do capacitors "decide" to discharge?
The capacitor discharge when the voltage drops from the main voltage level which it connected to like it connected between (5v and GND ) if voltage drops to 4.1v then the capacitor discharge some of its stored …
Why exactly do capacitors charge and discharge exponentially?
I understand that as a capacitor charges, the amount of electrons that are deposited on one plate increases, thereby the overall voltage across the capacitor increases. And I kind of understand that because of that, the rate at which 1 coulomb of charge flows in the circuit starts to fall because of this.

So my question is basically, what happens when we increase the distance separation of a capacitor without a battery? and then add a large voltage? Increasing the separation with the battery disconnected means that the capacitance of the capacitor decreases but the charge on the capacitor stays the same.
