alleryThe relation between conductivity κ, cell constant (l/A), and conductance G is:
Aκ = G + (l/A)
Bκ = G × (A/l)
Cκ = G − (l/A)
Dκ = G × (l/A)
Answer & Solution
Correct answer: D. κ = G × (l/A)
We have G = κ A/l → κ.
So G = G × (l/A).
**Cell constant = l/A**
multiplying conductance by the cell constant gives conductivity.
(Equivalently, κ = G*/R where G* is the cell constant.)
