What is cell constant what is its unit how is it determined

Dear student,

Cell constant is defined as the ratio of length of a cell to the cross-section area of cell.
​It is determined by the formula   l/A .

Another formula is G*= RK

where R = resistance of cell
​           K = kappa (inverse of conductivity)

​Cell constant is always constant however the concentration of cell changes.
s it is ratio of l/A hence unit is m-1 . Where 'l' is distance between electrodes and 'A' is cross section area .
