  1. Insulator (electricity) - Wikipedia

    • 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. The property that distinguishes an insulator is its resistivity; insulators have higher resistivity than … See more

    Physics of conduction in solids

    Electrical insulation is the absence of electrical conduction. Electronic band theory (a branch of physics) explains that electric charge flows when quantum states of matter are available into which electrons can be exci… See more

    Uses

    A flexible coating of an insulator is often applied to electric wire and cable; this assembly is called insulated wire. Wires sometimes don't use an insulating coating, just air, when a solid (e.g. plastic) coating may be imp… See more

    Insulation in electrical apparatus

    The most important insulation material is air. A variety of solid, liquid, and gaseous insulators are also used in electrical apparatus. In smaller transformers, generators, and electric motors, insulation on the wire … See more

    Telegraph and power transmission insulators

    Conductors for overhead high-voltage electric power transmission are bare, and are insulated by the surrounding air. Conductors for lower voltages in distribution may have some insulation but are often bare as wel… See more

  2. In an insulator, electrons completely fill the valence band; and the gap between it and the next band, which is the conduction band, is large. The electrons cannot move under the influence of an electric field unless they are given enough energy to cross the large energy gap to the conduction band.

    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.

    In a typical insulator, electrons are bound to individual atoms or molecules, preventing easy flow through the material. Conductors, in contrast, are characterized by the presence of free charges (typically electrons), which can move easily and thus allow charge to flow easily through the material.

    Electrical Insulators are materials that restrict the free flow of electrons from one particle to the other. If some amount of charge is transferred to an element at any point, the charge stays at the initial location and is not distributed across the surface.

    Insulators, or non-conductors, are materials that resist the flow of electrical charge. In insulators, electrons are tightly bound to their atoms, making them less free to move. This property makes insulators ideal for preventing unwanted electrical currents.
