Let''s say I have a parallel plate capacitor. How would I find the electric field at a certain point INSIDE the capacitor (inside the dielectric let''s say). From what I understand, the flux of the electric field will be constant everywhere (even if there is more than 1 different dielectric), but the electric field varies. Is this correct?
The negative charges inside the dielectric will be attracted towards the positive plate of the capacitor while the positive charges will be attracted towards the negatively charged plate of the capacitor, however these charges can travel only so far inside the dielectric, but if you see now the electric field created by the charges setup inside the dielectric will oppose …
Vector Calculus, The Electric Field Inside a Capacitor The Electric Field Inside a Capacitor Let the xy plane have a uniform charge density d spread across it.

The problem of determining the electrostatic potential and field outside a parallel plate capacitor is reduced, using symmetry, to a standard boundary value problem in the half space z0.
$begingroup$ The fields outside are not zero, but can be approximated as small for two reasons: (1) mechanical forces hold the two "charge sheets" (i.e., capacitor plates here) apart and maintain separation, and (2) there is an external source of work done on the capacitor by some power supply (e.g., a battery or AC motor). Remove (1) and the two "sheets" will begin to …
But not their charge. The charges on the two capacitors will be different. Thus electric field outside of dielectric in lower part of capacitor is not equal to the electric field in upper part of capacitor. Thus in order to avoid long approach, you can consider your book statement.(which I assume you understand) Altenatively:

The voltage across the capacitor after insertion of the bar is
The electric field is zero inside a space that is completely enclosed by a conductor. In a capacitor you have two plates that are electrically isolated. This allows for an electric field to be set up between the plates, and this in turn allows for the capacitor to store a certain amount of charge / energy, which is desirable for many electrical circuits. If you start …
In a parallel plate capacitor, the electric field E is uniform and does not depend on the distance d between the plates, since the distance d is small compared to the dimensions of the plates.

I know that the electric field is zero inside a conductor. However, a plate does not have some kind of "interior space." So, if there is a infinitely large conductor plate with a uniform charge density, what is the electric field made by the plate? Is it just the same as a plate with uniform charge distribution? It is so much confusing...

The electric field between the plates is (E=sigma / epsilon_{0}), where the charge per unit area on the inside of the left plate in figure 17.1 is (sigma=q / S .). The density on the right plate is just - (sigma).
Due to the charges on the plates of the capacitor, an electric field is produced inside the capacitor or in between the plates of the parallel plate capacitor.However, when a dielectric material is placed inside a capacitor or in between the plates of a parallel plate capacitor, the electric field in that space reduces.
The magnitude of the electrical field in the space between the plates is in direct proportion to the amount of charge on the capacitor. Capacitors with different physical characteristics (such as shape and size of their plates) store different …

The electric field strength inside a capacitor is affected by the distance between the plates, the voltage applied, and the dielectric material between the plates. The distance and voltage have a direct relationship with the electric field strength, while the type of dielectric material can alter the electric field strength due to its permittivity.

The equation C = Q / V C = Q / V makes sense: A parallel-plate capacitor (like the one shown in Figure 18.28) the size of a football field could hold a lot of charge without requiring too much work per unit charge to push the charge into the capacitor. Thus, Q would be large, and V would be small, so the capacitance C would be very large. Squeezing the same charge into a capacitor …
