Question

What is cell constant?

Answer 1

For a given cell, the ratio of separation (l) between the two electrodes divided by the area of cross-section (A) of the electrode is called the cell constant.
Cell constant = `l/A`

Answer 2

The area (A) of the electrodes and the distance (l) between the two electrodes are fixed in a conductivity cell. Therefore, the quantity `l/A` is a constant for a particular conductivity cell. This quantity is termed as cell constant.
