3 Terms and Definitions
GB/T 20245.1-2006 and as defined in the following terms and definitions apply to this document.
3.1
Electrolyte conductivity electrolyticconductance
In the electrolytic cell filled with a liquid, the potential difference between the conductance of the electrolyte at the ratio of the ion current and the charge movement at both ends, see
Formula (1).
G = IU
(1)
Where.
G --- electrolyte conductivity is measured in siemens (S);
I --- the current flowing through the electrolyte, in amperes (A);
U --- the potential difference across the electrodes, in volts (V).
Electrolyte resistance is the reciprocal of conductance electrolyte in ohms (Ω).
3.2
Electrolyte conductivity electrolyticconductivity
Conductivity of the electrolyte, formerly known as conductivity, (2) is defined by the formula.
k = jE
