Conductance Calculator
The Conductance Calculator is a valuable tool for those working in electrical engineering and physics. Conductance is the reciprocal of resistance and provides a measure of how easily electricity flows through a conductor. This calculator helps you determine the conductance based on the cross-sectional area, resistivity, and length of the conductor, using a straightforward formula.
Formula
To calculate conductance, use the formula:
Conductance (C) = Cross-Sectional Area (A) / (Resistivity (p) * Length (L))
In this formula:
- A represents the cross-sectional area of the conductor in square meters.
- p represents the resistivity of the material in ohm-meters.
- L represents the length of the conductor in meters.
How to Use
- Enter the cross-sectional area of the conductor in square meters.
- Input the resistivity of the material in ohm-meters.
- Enter the length of the conductor in meters.
- Click the “Calculate” button.
- The conductance will be displayed in Siemens (S).
Example
If the cross-sectional area of a wire is 0.01 square meters, the resistivity is 1.5 ohm-meters, and the length is 2 meters, the conductance can be calculated as follows:
Conductance = 0.01 / (1.5 * 2) = 0.00333 Siemens
