Question

What is meant by dielectric substance​

Answer 1

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 thematerial. Instead, electric polarization occurs.

Answer 2

Dielectric substances are those which have very poor conductivity of electricity.
