What is a conductor insulator?
An electrical insulator is a material in which electric current does not flow freely. The atoms of the insulator have tightly bound electrons which cannot readily move. Other materials—semiconductors and conductors—conduct electric current more easily.
In a conductor, electric current flows freely, but in an insulator, it cannot. Learn about conductors and insulators, their definition, examples, properties and more at BYJU'S.

- Silver is the most conductive element.
- Metals are a preferred choice of material for making electrical wire because they are good conductors of electricity.
- Superconductor
- A semiconductor is a material whose electrical conductivity falls between that of a conductor and an insulator. Example, Germanium and Silicon
- The purpose of a lightning rod is to protect structures from lightning damages by blocking the surges and guiding their currents to the ground.
- The resistivity of a conductor depends on Temperature The material with which the conductor is made of
May 3, 2024 · Insulators, often organic molecules, are primarily held together by strong covalent bonds, impeding electron movement and hindering electrical conductivity. Material factors like doping or impurities can also affect conductivity; for example, pure water is an insulator, but saltwater conducts due to free-floating ions.

Electrical insulators are used mainly as parts of electrical equipment. For example, the electrical wires which transfer electricity through households, are covered with insulation material to prevent any safety hazards.

- Electrical conductors are those materials that propagate the ease of flow of electricity throughout them.
- Insulators are materials that do not allow electric charges to flow freely through them.
- Examples for insulators are given below : plastic, rubber, wax, wood, glass, air, styrofoam
- General properties that affect the effectiveness of an insulator are: High resistivity Breakdown voltage Atomic structure Air permeability
- Disc Insulators: ( Types of Insulators ) As the name implies, the insulator has the form of a disc. Hence it is known as a disc insulator. These insulators are often found in high voltage transmission and distribution lines.
- Pin Insulators: ( Types of Insulators ) Pin insulators are often seen in power distribution lines. It is a device that protects a wire from physical support, such as a utility pole pin (wooden or metal dowel).
- Strain Insulators: ( Types of Insulators ) These insulators are intended to resist the stretch of a hung electrical wire or cable under mechanical stress.
- Post Insulators: ( Types of Insulators ) Because it is suited for varying voltage levels, it is a high voltage insulator developed for use in substations.
Electrical Insulators are materials that do not allow electric charges to flow freely through them. Conductors possess a property which we refer to as conductivityFor insulators, their efficiency is determined on the basis of how much resistance they provide to the flow of electricity.
About Transcript. A conductor is a material that allows electrons to flow freely through it, making it useful for carrying electric current. An insulatoris a material that resists the flow of electrons, so it does not allow electric current to pass through it.
