Breakdown Strength: The maximum electric field a dielectric can withstand before electrical breakdown occurs. The Role of Electric Field Inside Dielectric: Capacitors and Energy Storage
Figure 19.16(b) shows the electric field lines with a dielectric in place. Since the field lines end on charges in the dielectric, there are fewer of them going from one side of the capacitor to the other. So the electric field strength is less than if there were a vacuum between the plates, even though the same charge is on the plates.

Here we begin to discuss another of the peculiar properties of matter under the influence of the electric field. In an earlier chapter we considered the behavior of conductors, in which the charges move freely in response to an electric field to such points that there is no field left inside a conductor.Now we will discuss insulators, materials which do not conduct electricity.

The electric field strength is, thus, directly proportional to . Figure 2. Electric field lines in this parallel plate capacitor, as always, start on positive charges and end on negative charges. Since the electric field strength is proportional to the density of field lines, it is also proportional to the amount of charge on the capacitor.
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.

When a voltage is applied across the plates of a capacitor, an electric field is established between the plates. This electric field is responsible for storing the electrical energy in the capacitor. The strength of the electric field is directly proportional to the voltage applied and inversely proportional to the distance between the plates.
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone is a passive electronic component with two terminals.
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.
Since the electric field strength is proportional to the density of field lines, it is also proportional to the amount of charge on the capacitor. The field is proportional to the charge: E ∝ Q, (19.5.1) (19.5.1) E ∝ Q, where the symbol ∝ ∝ means “proportional to.”
• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.
Capacitance is a function of the capacitor’s geometry. Factors such as the area of the plates, the distance between the plates and the dielectric constant of the dielectric used in the construction of the capacitor all influence the resulting capacitance.
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 lines, and the field is not contained entirely between the plates.
A real capacitor is finite in size. Thus, the electric field lines at the edge of the plates are not straight lines, and the field is not contained entirely between the plates. This is known as edge effects, and the non-uniform fields near the edge are called the fringing fields.
