What is cell constant? What are its units?
Answer:
The quantity l/A is called cell constant denoted by the symbol, G*. It depends on the distance between the electrodes and their area of cross-section and has the dimension of length–1 and can be calculated if we know l and A.
Its unit are cm–1 ohm–1.
