  2. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    If water has even a tiny amount of such an impurity, then the ions can carry charges back and forth, allowing the water to conduct electricity far more readily. It is known that the theoretical maximum electrical resistivity for water is approximately 18.2 MΩ·cm (182 kΩ ·m) at 25 °C. [ 56 ]

  3. Electrostatic plotter - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_plotter

    An electrostatic plotter is a type of plotter that draws images on paper with an electrostatic process. They are most frequently used for Computer-Aided Engineering (CAE), producing raster images via either a Liquid Toner or a Dry Toner model. Liquid Toner models use toner that is positively charged and thus becomes attracted to paper's ...

    en.wikipedia.org/wiki/Water_(data_page)

    In the following table, material data are given with a pressure of 611.7 Pa (equivalent to 0.006117 bar). Up to a temperature of 0.01 °C, the triple point of water, water normally exists as ice, except for supercooled water, for which one data point is tabulated here. At the triple point, ice can exist together with both liquid water and vapor.

  5. Electrostatics - Wikipedia

    en.wikipedia.org/wiki/Electrostatics

    Therefore, the electrostatic field everywhere inside a conductive object is zero, and the electrostatic potential is constant. The electric field, E {\displaystyle \mathbf {E} } , in units of Newtons per Coulomb or volts per meter, is a vector field that can be defined everywhere, except at the location of point charges (where it diverges to ...

  6. Electrostatic detection device - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_detection_device

    An electrostatic detection device, or EDD, is a specialized piece of equipment commonly used in questioned document examination to reveal indentations or impressions in paper that may otherwise go unnoticed. It is a non-destructive technique (will not damage the evidence in question), allowing further tests to be carried out.

  7. Kelvin water dropper - Wikipedia

    en.wikipedia.org/wiki/Kelvin_water_dropper

    The Kelvin water dropper, invented by Scottish scientist William Thomson (Lord Kelvin) in 1867, [1] is a type of electrostatic generator. Kelvin referred to the device as his water-dropping condenser. The apparatus is variously called the Kelvin hydroelectric generator, the Kelvin electrostatic generator, or Lord Kelvin's thunderstorm.

  8. Electrorheological fluid - Wikipedia

    en.wikipedia.org/wiki/Electrorheological_fluid

    There are two main theories to explain the effect: the interfacial tension or 'water bridge' theory, [4] and the electrostatic theory. The water bridge theory assumes a three phase system, the particles contain the third phase which is another liquid (e.g. water) immiscible with the main phase liquid (e.g. oil).

  9. Electrochemical potential - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_potential

    Φ is the local electrostatic potential in V. In the special case of an uncharged atom, z i = 0, and so μ i = μ i. Electrochemical potential is important in biological processes that involve molecular diffusion across membranes, in electroanalytical chemistry, and industrial applications such as batteries and fuel cells.
