dielectric
n 1: a material such as glass or porcelain with negligible
electrical or thermal conductivity [synonym: {insulator},
{dielectric}, {nonconductor}] [ant: {conductor}]

Dielectric \Di`e*lec"tric\, n. [Pref. dia- electric.] (Elec.)
Any substance or medium that transmits the electric force by
a process different from conduction, as in the phenomena of
induction; a nonconductor, separating a body electrified by
induction, from the electrifying body.
[1913 Webster]

  • Dielectric - Wikipedia
    Dielectric relaxation is the momentary delay (or lag) in the dielectric constant of a material This is usually caused by the delay in molecular polarisation with respect to a changing electric field in a dielectric medium (e g , inside capacitors or between two large conducting surfaces)
  • Dielectric | Definition, Properties, Polarization | Britannica
    Dielectric, insulating material or a very poor conductor of electric current When dielectrics are placed in an electric field, practically no current flows in them because, unlike metals, they have no loosely bound, or free, electrons that may drift through the material
  • Home - Dielectric
    Dielectric holds more patents than any other antenna manufacturer in the world—some from as far back as 1942, others so new, they’re still in John’s “active” file
  • What Is a Dielectric? Definition and How It Works
    A dielectric is a material that doesn’t conduct electricity but responds to an electric field by shifting its internal charges slightly This response, called polarization, is what makes dielectrics useful in everything from capacitors to computer chips While all dielectrics are insulators, the term “dielectric” specifically highlights how a material behaves electrically when placed in
  • Dielectric Materials: Definition, Properties and Applications
    Key learnings: Dielectric Material Definition: A dielectric material is an electrical insulator that becomes polarized when exposed to an electric field, aligning its internal charges without conducting electricity Properties Overview: Key properties of dielectric materials include dielectric constant, strength, and loss—factors that influence their efficiency and application in technology
  • Dielectric strength - Wikipedia
    The theoretical dielectric strength of a material is an intrinsic property of the bulk material, and is independent of the configuration of the material or the electrodes with which the field is applied This "intrinsic dielectric strength" corresponds to what would be measured using pure materials under ideal laboratory conditions
  • What Is a Dielectric? Definition, Properties, and Uses
    A dielectric is a material that doesn’t conduct electricity but responds to an electric field by becoming internally polarized That polarization is what makes dielectrics useful: it allows them to store electrical energy, which is why they’re essential components in capacitors, circuit boards, and countless electronic devices
  • What Is a Dielectric Layer and How Does It Work?
    A dielectric layer is an electrically insulating material that becomes polarized when exposed to an electric field Unlike a conductor, where electrical charges flow freely, a dielectric prevents the bulk movement of charge, acting as an electrical barrier
  • 2. 5: Dielectrics - Physics LibreTexts
    Within the dielectric, the positive and negative charges just pair-off differently, leaving a continued neutral charge But on the surfaces, the separated charges don't pair-off with opposites, leaving a net charge on the two surfaces of the dielectric called polarization charge Figure 2 5 1 – Creation of Polarization Charge on a Dielectric
  • Dielectric Materials: Definition, Properties and Applications
    Dielectric materials are electrical insulators that store electric charges and support electrostatic fields They are used in devices like capacitors, transformers, antennas, sensors, and optical fibers This article explains what dielectric materials are, how they work, and their properties and applications What is a dielectric material?
