The amount of electric current traveling per unit cross-section area is called as current density and expressed in amperes per square meter.

Conductance is the expression of the ease of the passing of the electrons. Specific conductance is given for most analyses and was determined by means of a conductance bridge and using a standard potassium chloride solution as a reference.

Conductivity, in general, may be of many types. It could be electrical, ionic, hydraulic, or thermal conductivity. However, conductivity is basically defined as a material’s ability to conduct electricity or heat.

When we talk about electrical conductivity, the SI unit of conductivity is siemens per meter (S/m)
