Resistivity (ρ) = 1 / Conductivity (σ)
Here's how to convert conductivity to resistivity:
1. Identify the conductivity value: You'll need the conductivity value in the appropriate units (usually Siemens per meter (S/m)).
2. Calculate the reciprocal: Divide 1 by the conductivity value. This will give you the resistivity value in Ohm-meters (Ω·m).
Example:
Let's say you have a conductivity of 50 S/m. To convert this to resistivity:
* Resistivity (ρ) = 1 / Conductivity (σ)
* Resistivity (ρ) = 1 / 50 S/m
* Resistivity (ρ) = 0.02 Ω·m
Therefore, the resistivity of the material is 0.02 Ω·m.
Important notes:
* The units of conductivity and resistivity are inversely related. Siemens per meter (S/m) is the unit for conductivity, while Ohm-meters (Ω·m) is the unit for resistivity.
* This formula applies to both direct current (DC) and alternating current (AC) conductivity.
* The relationship between conductivity and resistivity is dependent on the material's properties, such as temperature and composition.
