Question

what r dielectrics?​

Answer 1

Answer:

A dielectric material is a substance that is a poor conductor of electricity, but an efficient supporter of electrostatic fields. It is a small piece (disc, cube, or rectangle) of ceramic or other low-loss dielectric material with a high relative dielectric constant εr, normally in the range of 10 to 100. 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. Instead, electric polarization occurs.

Answer 2

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. Instead, electric polarization occurs.
