What Happens When Capacitor Plates Are Pulled Apart?
In summary, when the capacitor plates are pulled farther apart, the charge remains constant while the potential difference increases. This results in an increase in potential energy. The use of the term "potential difference" can refer to both the voltage supplied by a battery and the voltage within a capacitor, depending on the context.

Does changing the gap between plates change the capacitor voltage?
Yes, the voltage increases. It seems most of us learned of this in school. My Physics professor had a setup with movable plates, and a very sensitive (actually, very high impedance) voltmeter. As the plates were pulled apart, the voltage went up. This comes from the elemental formula Q=CV. Pulling the plates apart lowers the capacitance.

Remember, that on a regular capacitor, there is an attractive force between the two oppositely charged plates and it is this force that is trying to stop the plates from being pulled-apart.

What happens if a capacitor is fully charged?
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 to capacitor's charge when the plates are moved further apart?
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.
What happens if a capacitor is discharged completely?
If you discharge the capacitor completely, then both plates have no charge and are neutral. The charge will remain however the energy will not be the same. There is energy stored in the electric field itself. If move the plates you will be doing work on the system. When you move the plates apart the voltage will increase.
How does distance affect voltage in a capacitor?
A capacitor has an even electric field between the plates of strength E E (units: force per coulomb). So the voltage is going to be E × distance between the plates E × distance between the plates. Therefore increasing the distance increases the voltage. I see it from a vector addition perspective.
What happens when plates of a fully charged capacitor are isolated?
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 if you double the distance of a capacitor?
So, doubling the distance will double the voltage. The electric field approximation will degrade significantly as x x gets larger than some fraction of some characteristic dimension of the plates. As we know, a capacitor consists of two parallel metallic plates.
