Conductivity to Resistance Calculator

Formula

The formula to calculate the Resistance (R) is:

\[ \text{R} = \frac{\text{L}}{\sigma \times \text{A}} \]

Where:

Resistance (R): The measure of opposition to the flow of electric current through a material, measured in Ohms.
Length of Material (L): The length of the material through which the current flows, measured in meters.
Conductivity (σ): The measure of a material's ability to conduct electric current, measured in Siemens per meter.
Cross-Sectional Area (A): The area of the material's cross-section, measured in square meters.

Let's say the length of the material (L) is 2 meters, the conductivity (σ) is 5 S/m, and the cross-sectional area (A) is 0.01 m². Using the formula:

\[ \text{R} = \frac{2}{5 \times 0.01} = 40 \text{ Ω} \]

So, the resistance is 40 Ω.
