The energy (U_C) stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up. When a charged capacitor is disconnected from ...

The opposing electric field reduces the overall electric field, which decreases the potential difference between the plates. Therefore, the capacitance of the plates increases; The capacitance of a capacitor can also …
For a maximum value of the parameter h = 2.0, the electric field strength along the axis of the capacitor, normalized to the field strength in the capacitor with infinite plates (h → ∞), changes from e z = 1.48 on the plate with potential V 0 to e z = 0.75 on the plate at zero potential (the grounded plate), taking the value 0.89 at the center.
In a parallel plate capacitor, when a voltage is applied between two conductive plates, a uniform electric field between the plates is created. However, at the edges of the two parallel plates, instead of being parallel and uniform, the electric field lines are slightly bent upwards due to the geometry of the plates. This is known as the fringing or edge effect (see figure 2).
If you gradually increase the distance between the plates of a capacitor (although always keeping it sufficiently small so that the field is uniform) does the intensity of the field change or does it stay the same? If the former, does it increase or decrease? The answers to these questions depends. on whether, by the field, you are referring to the (E)-field or the (D) …

To find the capacitance C, we first need to know the electric field between the plates. A real capacitor is finite in size. Thus, the electric field lines at the edge of the plates are not straight …
Now we gradually pull the plates apart (but the separation remains small enough that it is still small compared with the linear dimensions of the plates and we can maintain our approximation of a uniform field between the plates, and so the force remains (F) as we separate them). The work done in separating the plates from near zero to (d) is (Fd), and this must then equal …
A parallel plate capacitor is a device that can store electric charge and energy in the form of an electric field between two conductive plates. The plates are separated by a small distance and are connected to a voltage source, such as a battery. The space between the plates can be filled with air, a vacuum, or a dielectric material, which is an insulator that can be …

You can also see that for large plates using approximations electric field comes out to be independent of distance, so when your TA pulls the plates apart thr electric field does not change; However potential depends directly on both electric field and distance.
