    • … if this material is right for you. Advantages of spray insulators: • They have higher R-values per inch than traditional batted fiberglass. R-value is the measurement of thermal resistance used in the construction industry today. The higher the number a material is, the more effectively it insulates …

    • … of the frequent thunderstorms, the high altitude (where the air, being at a lower pressure, had a lower dielectric breakdown strength, making it easier to ionize), and the dryness of the air (minimizing leakage of electric charge through insulators). Also, the property was free and electric power …

    • … mechanical structure, minimize the friction plane or use material with a small friction coefficient and low electrical resistance. Also consider the use of an ionizer. In sections that come into contact with device lead terminals, use a material that dissipates static electricity. Ensure that no statically …

    • … as an abrasive. Other specialized applications also exist or are being developed, including use as semiconductors: some blue diamonds are natural semiconductors, in contrast to most other diamonds, which are excellent electrical insulators. Industrial-grade diamonds are either unsuitable for use …

    • Superconductors, materials that have no resistance to the flow of electricity, are one of the last great frontiers of scientific discovery. Not only have the limits of superconductivity not yet been reached, but the theories that explain superconductor behavior seem to be constantly under review …

Dry skin has a fairly high resistance to electric current. But when skin is moist or wet, it acts as a conductor …

    • Something different to distract myself with. A first note on resistances - In Diablo II, there were four magic types - poison, ice, lightning, and fire. In Schematica, there are also four attack types: Electricity - which covers both lightning and current, and is generally resisted with insulators …

    • … to manufacture PCBs) in 1929, PCB’s were quickly acclaimed as an industrial breakthrough. These chlorinated oils have a low degree of reactivity. They are not flammable, have high electrical resistance, good insulating properties and are very stable even when exposed to heat and pressure. All in all …

    • Conductors In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. “Conductor” implies that the outer …
