Long answer type questions with internal and parallel choice.Materials which allow electric current to pass through them are goodconductors of Electricity. What are the materials known as which donot allow electricity to pass through them easily? Also name thematerials which do not allow the electric current to pass through them.Illustrate your answer with suitable example.

Answer»

materials which donot allow current to pass through them are known as INSULATORS .for example : rubber, wood, plastic, etc

Insulators are the materials or substances which resist or don’t allow the current to flow through them.They are mostly solid in nature and are finding use in a variety of systems. They do not allow the flow of heat as well. The property which makes insulators different from conductors is its resistivity.Wood, cloth, glass, mica, and quartz are some good examples of insulators. Insulators are also protectorsas they give protection against heat, sound and of course passage of electricity. Insulators don’t have any free electrons and it is the main reason why they don’t conduct electricity.

Examples of Insulators

Glass is the best insulator as it has the highest resistivity.

Plastic is a good insulator and it finds its use in making a number of things.

Rubber is a common component in making tyres, fire-resistant clothes and slippers. This is because it is a very good insulator.

Applications of Insulators

Being resistive to flow of electron, insulators find application worldwide in a number of ways. Some of the common uses include:

Thermal Insulators, disallow heat to move from one place to another. We use them in making thermoplastic bottles, in fireproofing ceilings and walls.

Sound Insulators help in controlling noise level, as they are good in absorbance of sound. Therefore, we use them in buildings, conference halls, and buildings to make them noise free

Electrical Insulators hinder the flow of electron or passage of current through them. We use them extensively in circuit boards, high-voltage systems and also in coating electric wire and cables.

the answer is insulator example of insulator is plastic rubber

Materials which do not allow electricity to pass through them are called insulators.

rubber,wood,plastic are some of the examples
