CONDUCTANCE OF ELECTROLYTIC SOLUTIONS

 ☝The electrical resistance of any object is directly proportional to its  length, l, and inversely proportional to its area of cross section, A. That is,

  R =ρl/A.

 ☝The inverse of resistance is called conductance, G.

  G =  l/R = A/lρ  =k A/l.

☝The SI unit of conductance is siemen, represented by ‘S’ or Ω^-1.

☝The inverse of resistivity is called conductivity (specific conductance) κ.
