Does voltage drop with discharge? Since voltage is the potentiality between two charges to re-balance (from my understanding).
I mean, once all charges are equally shared between both capacitor sides, there is no potentiality between the charges to re-balance since they are now balanced.
Can we tell that voltage drops when a capacitor discharges?
If yes, does this mean that my 9V lithium battery loses voltage while being used?
That would also mean that a LED would lose brightness over time, is that the case?
