Which of the following statement is correct regarding dielectric materials?

CONCEPT:

• Dielectric: An electrically insulating material that becomes polarized in an electric field is called a dielectric.
• Only an insulator or poor conductor of electricity can be a dielectric material.
  • So that when the voltage applied, no current flows through it.
• Properties of dielectric:

1. A dielectric material can be solid, liquid, gas, or vacuum.
2. Dielectric is used for storing energy.
3. It is polarized when voltage is applied across the surface of the dielectric.

EXPLANATION:

• Dielectric is the materials through which current can not flow.
• So conductors can not be a dielectric material.
• So only poor conducting materials or insulators can be a dielectric material.
• Hence the correct answer is option 1.
