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

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 .
