conductivities, plural;
  1. The degree to which a specified material conducts electricity, calculated as the ratio of the current density in the material to the electric field that causes the flow of current. It is the reciprocal of the resistivity

  2. The rate at which heat passes through a specified material, expressed as the amount of heat that flows per unit time through a unit area with a temperature gradient of one degree per unit distance

  1. conduction: the transmission of heat or electricity or sound
  2. (conductive) having the quality or power of conducting heat or electricity or sound; exhibiting conductivity
  3. The 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).
  4. The ability of a material to conduct electricity, heat, fluid or sound; The reciprocal of resistivity
  5. (conductive) the ability to transfer electrical potential.
  6. (Conductive) A material that can discharge static electricity: A level of ESD material best suited for areas where items are not continuously grounded ex: carrying a bin. Rated at less than 10^5 Ohms.
  7. (CONDUCTIVE (CD)) Used in areas with extremely volatile materials.  Complete grounding is necessary, so as not to ignite munitions, fuel, etc.
  8. (Conductive) A material which has an electrical resistivity below 1x10^5 Ohms/sq.
  9. (Conductive) An adjective describing a material that transfers heat. Induction heating coils are usually made of copper, a highly-conductive metal.
  10. (Conductive) Suitable for carrying electric current.
  11. (conductive) able to pass heat or electricity from one side to the other.
  12. Conductive liners are made from conductive plastic that is engineered to adsorb an electrical charge and move it to ground.
  13. The word "conductive" has a range of meanings within the context of different standards and should be treated with care.
  14. The rate at which heat is transmitted through a material.
  15. The quality or power to carry electrical current; in water, the conductivity is related to the concentration of ions capable of carrying electrical current.
  16. The quantity of heat that will flow through one square foot of homogeneous material, one inch thick, in one hour, when there is a temperature difference of one degree Fahrenheit between its surfaces.
  17. The electrical property of a sheet of paper which enables it to attract charged toner. Low conductivity can result in poor image quality in digital systems.
  18. This is a positive constant, k, that is a property of a substance and is used in the calculation of heat transfer rates for materials. ...
  19. The ability of a mineral to transmit heat, electricity, or sound.
  20. The capability of a material to carry electrical current-usually expressed as a percentage of copper conductivity (copper being 100%).
  21. Measure of the ability of water to conduct electrical current.  It is directly related to the total dissolved substances in the water.
  22. The ability of an aqueous solution to carry electric current depends on the presence of ions in the solution.  Conductivity is a quantitative measure which describes this ability. ...
  23. An electrical property of seawater which depends on the amount of dissolved materials (primarily NaCl). Measures of conductivity can be used (with other variables) to calculate seawater’s salinity.
  24. The capacity of living matter to conduct action potentials.
  25. The theoretical definition of conductivity is the "reciprocal of the resistance of a cube of a substance 1 cm on a side at a specified temperature". Typically the units of measure are microhms/cm (uohms/cm) or microsiemens/cm (uS/cm). ...
