The conductance of a solution is a measure of its capacity to transport a current. The mobility of ions causes the passage of electricity through the solution. A solution’s conductivity (к) is defined as,
к = j/E.
j = Density of electric current
E denotes the strength of the electric field
Conductance is a measure of how easily electric current passes through a material. Conductance is represented in equations by the capital letter G. The siemens (S), formerly known as the mho or ohm-1, is the standard unit of conductance.
