Specific conductance (Κ) is related to resistivity as
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → $Κ=\frac{1}{ρ}$
- Resistivity (ρ) is the resistance of a material of unit length and unit cross-section.
- Specific conductance (κ) (also called conductivity) is the reciprocal of resistivity.
$\kappa = \frac{1}{\rho}$
