WebElectrical conductivity (EC) measures how well a substance can transmit an electrical current. Small charged particles, called ions, help to carry the electrical charge through a substance. These ions can be positively or negatively charged. The more ions available, the higher the conductivity; fewer ions would result in lower conductivity. EC is typically … Webwhere σ w is the pore water electrical conductivity (dS/m); ε w is the real portion of the dielectric permittivity of the soil pore water (unitless); σ b is the bulk electrical conductivity, (dS/m), which is measured directly by …
