Question

When measuring conductivity with a conductivity cell, cell constant denoted by the symbol G* is given by (electrode area of cross-section equal to ‘A’ and separated by distance ‘l’)

Options

• G* = `(2"l")/"A"`

• G* = `"l"/"A"`

• G* = lA

• G* = `"A"/"l"`

Answer 1

G* = `"l"/"A"`

Explanation:

Cell constant is the ratio between the distance between electrodes (l) of the cell to the area of cross-section of electrodes (A).
