Definitions for "Electrical conductivity"
conductivity; electric conductivity; electrical conductance; conductance. Compare with resistance. A measure of how easily an electric current can pass through a material. The conductivity is the reciprocal of the resistance. The SI unit of conductance is the siemens.
Conductivity is a measure of the capacity of an aqueous solution to carry an electrical current. Conductivity is commonly used to determine salinity and is mostly reported in microSiemens per centimetre (mS/cm) or milliSiemens per metre (mS/m) at a standard reference temperature of 25° Celsius.
When a voltage is applied across a substance, an electric current will only flow if the substance conducts electricity. When salts dissolve in water, ions are formed and the solution (the electrolyte) will conduct electricity. As a general rule, the higher the concentration of ions in solution (ie, the higher the salt concentration) the better the solution conducts electricity; in other words, its electrical conductivity increases. Electrical conductivity is often expressed in units such as deciSeimens per metre (dS/m). Rain water, for example, has a conductivity of 0.02-0.05 dS/m, while sea water has a conductivity of 50-60 dS/m.
