Definition Of Insulator

Posted on

A material that maintains a tight grip on its electrons so that an electric current cannot pass through it within voltage limits. Insulator any of various substances that block or retard the flow of electrical or thermal currents.

Thermal insulations consist of low thermal conductivity materials combined to achieve an even lower system thermal conductivityThermal insulation can be achieved with specially engineered methods or processes as well as with suitable.

Definition of insulator. ˈɪnsəleɪtɚ a material or covering that electricity heat or sound cannot go through. A device that insulates. A material that does not easily transmit energy such as electric current see also current or heat.

Fiberglass is an example of a heat insulator. The covalent bond between the atoms of an insulator is very strongThus the electrons or charges do not move freely. Materials such as wood plastic and ceramics are insulators.

If we transfer some amount of charge to such an element at any point the charge remains at the initial location and does not get distributed across the surface. The resistivity of the insulator is very high. A material that will not conduct current to an appreciable degree.

A material that insulates especially a nonconductor of sound heat or electricity. This type of material is called an insulator. An insulating material used in bulk to wrap electrical cables or other equipment is called insulation.

Generally plastics tend to be good insulators. Insulators are used in electrical equipment to support and separate electrical conductors without allowing current through themselves. A material that contains these types of atoms has very few if any free electrons and does not transfer electrical energy well if at all.

Soundproofing material is an example of an insulator. Any material that keeps energy such as electricity heat or cold from easily transferring through is an insulator. The division of materials into the categories of conductors and insulators is a.

Examples of conductors include metals aqueous solutions of salts ie ionic compounds dissolved in water graphite and the human body. ARRL Ham Radio Glossary. A substance that doesnt conduct electricity well is an example of an insulator.

A material that allows little or no heat electricity or sound to go into or out of something See the full definition for insulator in the English Language Learners Dictionary. Examples of insulators include plastics Styrofoam paper rubber glass and dry air. Thermal insulation is the process of reduction of heat transfer between objects in thermal contact or in range of radiative influence.

Materials that do not conduct heat or electricity are known as insulators. Information and translations of insulator in the most comprehensive dictionary definitions resource on the web. Insulators contain clustered binding sites for sequence specific DNA-binding proteins and mediate intra- and inter-chromosomal interactions.

An insulator is a type of cis-regulatory element known as a long-range regulatory elementFound in multicellular eukaryotes and working over distances from the promoter element of the target gene an insulator is typically 300 bp to 2000 bp in length. Report an issue with this definition. Insulators and conductors have many useful functions.

The idea of an insulator comes from the Latin idea of insulātus which means to make into an island. Generally plastics tend to be good insulators. Examples of Conductors and Insulators.

The definition of an insulator is something that is used to keep heat or sound contained or something that does not conduct electricity. Insulators are materials that hinder the free flow of electrons from one particle of the element to another. Materials that conduct heat or electricity are known as conductors.

English Language Learners Definition of insulator. Wood plastic rubber and glass are good insulators. ˈɪnsjəleɪtə r a material or covering that electricity heat or sound cannot go through.

The materials which do not allow the electric current or heat to pass through it such type of material is called an insulator. Swiss cheesenot so much.
