Capacitors
We will use Gauss''s Law to calculate the magnitude of the electric field between the two plates, far away from the edges. We can imagine a Gaussian surface Σ as shown in Figure 9.That is, Σ is the surface of a small rectangular parallelepiped, half of which lies outside the capacitor, and whose base faces are parallel to the plates. ...
18.5 Capacitors and Dielectrics
With the electric field thus weakened, the voltage difference between the two sides of the capacitor is smaller, so it becomes easier to put more charge on the capacitor. Placing a dielectric in a capacitor before charging it therefore allows more charge and potential energy to be stored in the capacitor.
Electric Field Strength in a Capacitor. Online Calculator.
A spherical capacitor is a capacitor whose plates are two concentric spheres with radii R 1 and R 2, between which there is a dielectric whose permittivity is ε. The electric field strength in a spherical capacitor is determined by the formula, where Q - electric charge

Electric Field | Fundamentals | Capacitor Guide
The electric field strength in a capacitor is directly proportional to the voltage applied and inversely proportional to the distance between the plates. This factor limits the maximum rated voltage of a capacitor, since the electric field strength must not exceed the breakdown field strength of the dielectric used in the capacitor.

Two parallel-plate air capacitors, each of capacitance C, were connected in series to a battery with emf ϵ. Then one of the capacitors was filled up with uniform dielectric with permittivity ϵ. How many times did the electric field strength in that capacitor decrease
Electric field in a parallel plate capacitor
A capacitor is a device used in electric and electronic circuits to store electrical energy as an electric potential difference (or an electric field) consists of two electrical conductors (called plates), typically plates, cylinder or sheets, separated by an insulating layer (a void or a dielectric material). ...

13.1: Electric Fields and Capacitance
The greater the difference of electrons on opposing plates of a capacitor, the greater the field flux, and the greater "charge" of energy the capacitor will store. Because capacitors store the potential energy of accumulated electrons in the form of an electric field, they behave quite differently than resistors (which simply dissipate energy in the form of heat) …
