Conductivity (`kappa`), conductance (G) and cell constant `(G^(@))` are related as___.

Explanation

To solve the question regarding the relationship between conductivity (κ), conductance (G), and cell constant (G^(@)), we will follow these steps:

### Step 1: Understand the Definitions
- **Conductivity (κ)**: It is defined as the ability of a solution to conduct electricity, represented as κ = 1/ρ, where ρ is the resistivity of the solution.
- **Conductance (G)**: It is the measure of how easily electricity flows through a material, defined as G = 1/R, where R is the resistance.
- **Cell Constant (G^(@))**: It is defined as the ratio of the length (L) of the conductive path to the cross-sectional area (A) of the conductor, given by G^(@) = L/A.

### Step 2: Relate Resistance to Resistivity
