Question

The cell constant is defined as the ratio of ____________

(a) Area of either electrodes to the length between the electrodes

(b) Length between the electrodes to the area of either electrodes

(c) Length between the electrodes to the volume of either electrode

(d) Resistivity to conductivity

I have been asked this question at a job interview.

My doubt is from Conductivity in portion Criteria of Purity and Characterisation of Materials of Engineering Chemistry I

Answer 1

Correct choice is (b) Length between the electrodes to the area of either electrodes

The best I can explain: The cell constant is defined as the ratio of length between the electrodes to the area of either electrodes. It only depends upon the physical dimension of the cell.
