Insulator Material

In summary, a dielectric material is a non-conductive material that can store and transmit electrical energy by resisting the flow of electric current. It acts as an insulator by polarizing electrons and preventing their flow. Common examples include rubber, glass, plastic, and ceramics. Although rare, dielectric materials can become conductive under high electric fields, known as dielectric breakdown. They are commonly used in electronic devices as insulators and in capacitors to increase capacitance and improve circuit efficiency.

When a dielectric material insert between two plate capacitors the conductivity may increase.
Normally we talk that a dielectric is insulator?but how can it increases
conductivity?

Do you mean capacitance will increase?

1. What is a dielectric material?

A dielectric material is a type of insulating material that can store and transmit electrical energy. It is a non-conductive material that is able to resist the flow of electric current.

2. How does a dielectric material act as an insulator?

A dielectric material acts as an insulator due to its ability to prevent the flow of electrons. When an electric field is applied, the electrons in the material become polarized, creating a barrier that hinders the flow of current.

3. What are some examples of dielectric materials?

Some common examples of dielectric materials include rubber, glass, plastic, and ceramic materials. These materials are often used in electrical insulation applications due to their high resistivity to electric current.

4. Can a dielectric material become conductive?

Yes, a dielectric material can become conductive under certain conditions. If the electric field applied is strong enough, the electrons in the material may gain enough energy to break free and start conducting electricity. This is known as dielectric breakdown.

5. How is a dielectric material used in electronic devices?

Dielectric materials are commonly used in electronic devices as insulators to prevent short circuits and to store electrical energy. They are also used in capacitors to increase their capacitance and to improve the efficiency of electronic circuits.
