When battery disconnected from capacitor, the charge stored in the capacitor remains the same. The voltage across the capacitor also will remain the same. Q. A capacitor is charged with a battery and then removed from the battery. In this specially designed capacitor, we are able to make the plate size (area) larger without changing anything else.
When the bottom connection is made, the bottom plates of both capacitors are connected, and depending on the initial states (charge bias) of the two capacitors, charge could be transferred. For example, the uncharged capacitor could have have any charge on both plates, as long as the charges were equal.
why does charge stored in capacitor remain constant. Because you disconnected the voltage source. It's meant to be implied that the capacitor is disconnected from all external circuits. Therefore there's nowhere for the charge to go. And since charge is a conserved quantity, that means the charge on the capacitor plate must remain constant.
I understand that when the separation between the plates of a charged capacitor is increased, the voltage increases. But I'd really like to know what happens to the plates if the capacitor is fully charged , disconnected from the charging circuit and then the plates are moved apart from each other by an infinite distance.
What happens when plates of a fully charged capacitor are isolated from each other? I'm a mechanical engineering student and I'm working on a project that involves a high voltage capacitor. I understand that when the separation between the plates of a charged capacitor is increased, the voltage increases.
What happens to capacitor’s charge when the plates are moved further apart? In my physics textbook there is an example of using capacitor switches in computer keyboard: Pressing the key pushes two capacitor plates closer together, increasing their capacitance.
The capacitor is then disconnected from the battery, and the spacing between the capacitor plates is tripled. As a result of this change, what is the An air-filled parallel plate capacitor with area …
When a capacitor is disconnected from the power supply, it retains the charge that was stored in it. This happens because there is no conductive path for the charge to dissipate. The dielectric …

If the capacitor has a voltage across its plates and the supply is disconnected, the charge remains irrespective of the distance so, if distance increases (and capacitance falls) …
Capacitance and energy stored in a capacitor can be calculated or determined from a graph of charge against potential. Charge and discharge voltage and current graphs for capacitors.
When the battery is disconnected, a capacitor will retain the charge it has stored. However, without a power source, the capacitor will eventually discharge over time …
