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 .
Regards
