This tool will help you calculate the resistivity of a material based on its resistance, length, and cross-sectional area.

## Resistivity Calculator

This resistivity calculator helps you determine the electrical resistance of a material based on its resistivity, length, and cross-sectional area. Enter the resistivity of the material (in ohm-meter), the length of the material (in meters), and the cross-sectional area (in square meters). Click “Calculate” to find the resistance in ohms.

### How to Use

- Enter the resistivity (ρ) of the material in ohm-meter.
- Enter the length (L) of the material in meters.
- Enter the cross-sectional area (A) of the material in square meters.
- Click the “Calculate” button to obtain the resistance (R) in ohms.

### Calculation Method

The resistance of a material is calculated using the formula:

**R = (ρ * L) / A**

Where:

**R**is the resistance in ohms (Ω).**ρ**is the resistivity of the material in ohm-meter (Ω⋅m).**L**is the length of the material in meters (m).**A**is the cross-sectional area of the material in square meters (m²).

### Limitations

This calculator provides accurate results based on the input values. However, it does not account for factors such as temperature variations, impurities in the material, or other environmental influences that may affect the actual resistance of the material.
