What does the capacitor plate remain unchanged when grounded
A parallel plate capacitor with a dielectric between its plates has a capacitance given by (C=kappa varepsilon _{0} dfrac{A}{d},) where (kappa) is the dielectric constant of the material. The maximum electric field strength above which an insulating material begins to break down and conduct is called dielectric strength.

The force will decrease if the capacitor is charged and not connected to a voltage source when the dielectric is inserted. The force will remain the same if the charged capacitor is connected to a voltage source when the dielectric is inserted.
Solved Qualitatively, how does the capacitor voltage change
Question: Qualitatively, how does the capacitor voltage change (increase, decrease, stay the same) as the plateseparation is increased? Explain this behavior using the work-energy principle. Qualitatively, how does the capacitor voltage change ( increase, decrease, stay the same ) as the
How does distance effect the flow of charges between a capacitor…
Q=CV C, the capacitance is inversely proportional to the distance. Since the plates are still attached to the battery, V, the potential difference will remain unchanged. However since the capacitance drops as a result of the increasing distance between plates, Q, the charge on the plates should be changed. So charges will flow back to the battery.
electrostatics
When the dielectric is inserted in between the plates of an isolated capacitor, the electric field E inside the dielectric decrease k times. Outside the dielectric, at the location where plates are situated, electric field is same as before, hence the force between them don''t change.

Why does a floating capacitor act differently than a grounded capacitor?
I''m having difficulty understanding why a floating capacitor will store less charge than a grounded capacitor. Imagine you have two parallel plates and a low DC voltage source like 5V, with the negative side connected to neutral ground, and that you have two different ways of wiring it: ... since they are close together. And if the neutral ...
Intuitive explanation for uniform electric field between capacitor plates
$begingroup$ @CuriousOne yeah, and if I keep the charge constant, and increase the distance, the electric field will stay constant - why? If I place a test charge half a distance between the plates, and write down the electric force acting on it, and then move each plates 100m away from the charge, how can it be that the force acting on the test charge will remain unchanged?
electrostatics
$begingroup$ I think you mean Capacitance of capacitor made with metal, In this case, It is infact the opposite, The capacitance is intrinsic property of any capacitor, This intrinsic property arises from the geometry of the components involved, primarily the arrangement and separation of conductive plates in a capacitor.
Is there a physical explanation for why increasing a capacitor''s ...
A larger capacitor has more energy stored in it for a given voltage than a smaller capacitor does. Adding resistance to the circuit decreases the amount of current that flows through it. Both of these effects act to reduce the rate at which the capacitor''s stored energy is dissipated, which increases the value of the circuit''s time constant.

The amount of charge Q a capacitor can store depends on two major factors—the voltage applied and the capacitor''s physical characteristics, such as its size. A system composed of two identical, parallel conducting plates …
The potential difference between the plates
If a dielectric slab is inserted between the plates of a charged capacitor, the intensity of electric field potential difference of capacitor and the energy stored all reduce to K 1 times and K. capacity of the capacitor increases K times. But the charge on the capacitor remains unchanged. Here K is the dielectric constant of dielectric.
Capacitor charging and Energy storage
An external voltage source, such as a battery, does work to remove electrons from one plate and deposit them on the other, resulting in a net negative charge on one plate and net positive charge on the other. The total electrical charge (protons and electrons) on the plates remain unchanged.
Capacitance of a Grounded Capacitor
Actually, when an uncharged plate is grounded its charge remains always zero. But if a charged plate is brought near to the uncharged plate, a induced potential of the same type developed at the far side of the grounded plate which is neutralized by the ground and …
capacitance
The capacitor only works right if we pretend that it''s some sort of wire. With wires, if we try to push in more charge than we remove, both ends of the wire immediately charge up to fantastic values of voltage, and this blocks any further current. A capacitor in electronics does the same thing. More: the engineer''s capacitor. Why does this occur?
