Bookmark or Share- What is a dielectric material and how does it work? - TechTargetA dielectric material is a poor conductor of electricity but an efficient supporter of electrostatic fields. It can store electrical charges, have a high specific resistance and a negative temperature coefficient of resistance. More about dielectric materials.
- Dielectrics - HyperPhysicsThe dielectric must be a good electric insulator so as to minimize any DC leakage current through a capacitor. The presence of the dielectric decreases the electric field produced by a given charge density. The factor k by which the effective field is decreased by the polarization of the dielectric is called the dielectric constant of the material.
- Dielectrics article (article) | Khan AcademyWhat 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.
- 2.5: Dielectrics - Physics LibreTextsSuch substances are called dielectrics, and they actually provide an effect similar to what is seen in conductors, though it is not extreme enough to completely cancel the field. Start with a slab of neutrally-charged dielectric located between two neutrally-charged conductor plates.
- Dielectric - WikipediaIn electromagnetism, a dielectric (or dielectric medium) is an electrical insulator that can be polarised by an applied electric field.
