  2. Mineral-insulated copper-clad cable - Wikipedia

    en.wikipedia.org/wiki/Mineral-insulated_copper...

    Conductor cross section area is 1.5 mm 2; overall diameter is 7.2 mm. Mineral-insulated copper-clad cable is a variety of electrical cable made from copper conductors inside a copper sheath, insulated by inorganic magnesium oxide powder. The name is often abbreviated to MICC or MI cable, and colloquially known as pyro (because the original ...

  3. Standard electrode potential (data page) - Wikipedia

    en.wikipedia.org/wiki/Standard_electrode...

    The data below tabulates standard electrode potentials ( E °), in volts relative to the standard hydrogen electrode (SHE), at: Absolute partial pressure 101.325 kPa (1.00000 atm; 1.01325 bar) for each gaseous reagent — the convention in most literature data but not the current standard state (100 kPa). The Nernst equation allows to calculate ...

  4. ABC dry chemical - Wikipedia

    en.wikipedia.org/wiki/ABC_dry_chemical

    Dry chemical powder is used on all classes of fires. Dry chemical powder puts out the fire by coating the burning material with a thin layer of dust, thereby separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out the fire.

  5. American wire gauge - Wikipedia

    en.wikipedia.org/wiki/American_wire_gauge

    American Wire Gauge ( AWG) is a logarithmic stepped standardized wire gauge system used since 1857, predominantly in North America, for the diameters of round, solid, nonferrous, electrically conducting wire. Dimensions of the wires are given in ASTM standard B 258. [ 1] The cross-sectional area of each gauge is an important factor for ...

  6. International Annealed Copper Standard - Wikipedia

    en.wikipedia.org/wiki/International_Annealed...

    The International Annealed Copper Standard ( IACS) is a standard established in 1914 by the United States Department of Commerce. [ 1] It is an empirically derived standard value for the electrical conductivity of commercially available copper . Sometime around 1913 several copper samples from 14 important refiners and wire manufacturers were ...

  7. Caesium chloride - Wikipedia

    en.wikipedia.org/wiki/Caesium_chloride

    The caesium chloride structure adopts a primitive cubic lattice with a two-atom basis, where both atoms have eightfold coordination. The chloride atoms lie upon the lattice points at the corners of the cube, while the caesium atoms lie in the holes in the center of the cubes; an alternative and exactly equivalent 'setting' has the caesium ions at the corners and the chloride ion in the center.

  8. Electrochemical equivalent - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_equivalent

    Electrochemical equivalent. In chemistry, the electrochemical equivalent ( Eq or Z) of a chemical element is the mass of that element (in grams) transported by a specific quantity of electricity, usually expressed in grams per coulomb of electric charge. [ 1] The electrochemical equivalent of an element is measured with a voltameter .

  9. Conductivity (electrolytic) - Wikipedia

    en.wikipedia.org/wiki/Conductivity_(electrolytic)

    Conductivity (electrolytic) Conductivity or specific conductance of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is siemens per meter (S/m). Conductivity measurements are used routinely in many industrial and environmental applications as a fast, inexpensive and reliable way of ...
