WEBthe basic idea. Dielectrics are insulators, plain and simple. The two words refer to the same class of materials, but are of different origin and are used preferentially in different contexts. Since charges tend not to move easily in nonmetallic solids it's possible to have "islands" of charge in glass, ceramics, and plastics.

WEBWhat are dielectrics? Dielectrics are materials that don’t allow current to flow. They are more often called insulators because they are the exact opposite of conductors. But usually when people call insulators “dielectrics,” it’s because they want to draw attention to a special property shared by all insulators: polarizability.

WEBWhen a dielectric is placed between charged plates, the polarization of the medium produces an electric field opposing the field of the charges on the plate. The dielectric constant k is defined to reflect the amount of reduction of effective electric field as shown below. The permittivity is a characteristic of space, and the relative permittivity or …
