Capacitor: device that stores electric potential energy and electric charge. Two conductors separated by an insulator form a capacitor. The net charge on a capacitor is zero. To …
When the capacitor is filled with the dielectric liquid, its capacitance becomes kC, where k is the dielectric constant of the liquid. This increases the charge stored on each plate to kCV. The additional charge of (k - 1)CV came through the battery, which did some work, given by ΔqV = (k - 1)CV 2 .
As a dielectric material sample is brought near an empty charged capacitor, the sample reacts to the electrical field of the charges on the capacitor plates. Just as we learned in Electric Charges and Fields on electrostatics, there will be the induced charges on the surface of the sample; however, they are not free charges like in a conductor, because a …

where κ κ (kappa) is a dimensionless constant called the dielectric constant. Because κ κ is greater than 1 for dielectrics, the capacitance increases when a dielectric is placed between the capacitor plates. The dielectric constant of several materials is.

Note also that the dielectric constant for air is very close to 1, so that air-filled capacitors act much like those with vacuum between their plates except that the air can become conductive if the electric field strength becomes too great. (Recall that E = V / d E = V / d size 12{E=V/d} {} for a parallel plate capacitor.) ...
Introduction to the Properties of Plastic and Elastomer Films Laurence W. McKeen, in Film Properties of Plastics and Elastomers (Third Edition), 20122.4.1 Dielectric Constant (or Relative Permittivity) The dielectric constant is an essential piece of information when designing thin film capacitors and in other circumstances where a material might be …
The capacitance is maximized if the dielectric constant is maximized, and the capacitor plates have large area and are placed as close together as possible. If a metal was used for the dielectric instead of an insulator the field inside the metal would be zero, corresponding to an infinite dielectric constant.
We introduced the dielectric constant and then the permittivity as a means of ignoring the polarization charge. That is, the capacitance with a dielectric still satisfies (Q=CV), where (Q) is the charge on the plates, …
