Resistivity
Resistivity is the reciprocal of conductivity. It feeds directly into sheet resistance.
Inputs
Result
Enter values and calculate to see the result.
Interpretation
Enter a conductivity to get the resistivity.
Formula
ρ = 1 / σ
Reciprocal of conductivity.
Variables
| Symbol | Variable | Unit |
|---|---|---|
| ρ | Resistivity | Ω·m (shown as Ω·cm too) |
| σ | Conductivity | S/m |
Assumptions & validity
This tool assumes:
- Uniform, isotropic material.
- Resistivity is the inverse of conductivity at the same conditions.
Worked example
σ = 100 S/m.
ρ = 1 / 100 = 0.01 Ω·m = 1 Ω·cm
