Exempel på hur du använder INSULATORS i en mening

• The property that distinguishes an insulator is its resistivity; insulators have higher resistivity than semiconductors or conductors.
• These include transistors, capacitors, inductors, resistors, diodes and (naturally) insulators and conductors can all be found in microelectronic devices.
• It is an electrically neutral quasiparticle that exists mainly in condensed matter, including insulators, semiconductors, some metals, but also in certain atoms, molecules and liquids.
• Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams.
• The field of spintronics concerns spin-charge coupling in metallic systems; the analogous effects in insulators fall into the field of multiferroics.
• Objects made of electrical insulators like rubber tend to have very high resistance and low conductance, while objects made of electrical conductors like metals tend to have very low resistance and high conductance.
• In graphs of the electronic band structure of solids, the band gap refers to the energy difference (often expressed in electronvolts) between the top of the valence band and the bottom of the conduction band in insulators and semiconductors.
• End applications include tableware, decorative ware such as figurines, and products in technology and industry such as electrical insulators and laboratory ware.
• The materials used are typically filled with air pockets, slowing down the conduction of heat through the pad, as air is one of the best (and cheapest) insulators.
• It therefore requires spacing around rain gutters, spaced away from metal fences, exterior wall siding, and metal roofs, and mounted on standoff insulators when run up metal antenna masts.
• Extended to a lattice of magnetic impurities, the Kondo effect likely explains the formation of heavy fermions and Kondo insulators in intermetallic compounds, especially those involving rare earth elements such as cerium, praseodymium, and ytterbium, and actinide elements such as uranium.
• Paper, rubber, plastics, petrochemicals, carbon insulators, and abrasives composed the city's major industries.
• These charge imbalances have electrostatic effects that extend deeply into semiconductors, insulators, and the vacuum (see doping, band bending).
• The towers are usually steel lattices or trusses (wooden structures are used in Australia, Canada, Germany, and Scandinavia in some cases) and the insulators are either glass or porcelain discs or composite insulators using silicone rubber or EPDM rubber material assembled in strings or long rods whose lengths are dependent on the line voltage and environmental conditions.
• A semimetal also differs from an insulator or semiconductor in that a semimetal's conductivity is always non-zero, whereas a semiconductor has zero conductivity at zero temperature and insulators have zero conductivity even at ambient temperatures (due to a wider band gap).
• Two types of strainers are used: lattice towers similar to the suspension towers, but equipped with strainer insulators and of stronger design and much more often pole-type towers with a central pole supported by two diagonal bars.
• In general, they are electrical insulators, but become semiconducting when charges are injected from appropriate electrodes or are introduced by doping or photoexcitation.
• The same principle used in glass wool is used in other man-made insulators such as rock wool, Styrofoam, wet suit neoprene foam fabrics, and fabrics such as Gore-Tex and polar fleece.
• At one time Temuka supported wool scouring plants, it had a flour mill and manufactured electric power transmission insulators.
• Although Hemingray was best known for its telegraph insulators, the company produced many other glass items including bottles, fruit jars, pressed glass dishes, tumblers, battery jars, fishbowls, lantern globes, and oil lamps.
