electrostatics

Another useful and slightly more intuitive way to think of this is as follows: inserting a slab of dielectric material into the existing gap between two capacitor plates tricks the plates into thinking that they are closer to one another by a factor equal to the relative dielectric constant of the slab. As pointed out above, this increases the capacity …

8.4 Capacitor with a Dielectric

The constant κ κ in this equation is called the dielectric constant of the material between the plates, and its value is characteristic for the material. A detailed explanation for why the dielectric reduces the voltage is given in the next section. Different materials have different dielectric constants (a table of values for typical materials is provided in the next section).

19.5 Capacitors and Dielectrics

A capacitor is a device used to store electric charge. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators. Typically, commercial capacitors have two conducting parts close to one another, but not touching, such as those in Figure 19.13. (Most of the time an insulator is used between the two …

8.6: Molecular Model of a Dielectric

The dielectric strength imposes a limit on the voltage that can be applied for a given plate separation in a capacitor. For example, the dielectric strength of air is (E_c = 3.0, MV/m), so for an air-filled capacitor with a plate separation of (d = 1.00, mm), the limit on the potential difference that can be safely applied across its ...

Modeling Dielectric Absorption in Capacitors

dielectric absorption. The amount of dielectric absorption a capacitor exhibits is highly dependent on the dielectric material: polystyrene, polypropylene, and teflon display very little absorption, while ceramic is a much poorer performer. SiO2 displays about 0.1% dielectric absorption, putting its performance in the middle of the pack [12,16].

Double-layer capacitance

Double-layer capacitance is the important characteristic of the electrical double layer [1] [2] which appears at the interface between a surface and a fluid (for example, between a conductive electrode and an adjacent liquid electrolyte).At this boundary two layers of electric charge with opposing polarity form, one at the surface of the electrode, and one in …

5.14: Mixed Dielectrics

Gauss''s law is that the total (D)-flux arising from a charge is equal to the charge, so that in this geometry (D = sigma), and this is not altered by the nature of the dielectric materials between the plates. Thus, in this capacitor, (D = CV_0/A = Q/A) in both media. Thus (D) is continuous across the boundary.
