Final answer:
A dielectric material is an insulator that does not allow charge to move through it easily. It becomes polarized in an electric field, making it suitable for use in capacitors.the correct answer is insulator.
Step-by-step explanation:
A dielectric material is classified as an insulator in terms of conducting electricity. It does not allow charge to move through it easily, unlike conductors. Dielectrics become polarized in an electric field, which means their molecules shift their electrons in response to the field but do not let them escape completely from their atoms. This property makes them suitable for use in capacitors, as they can store electrical energy.
