Wire Resistance Calculator

Calculate the electrical resistance of a wire using:
\[ R = \rho \, \frac{L}{A} \]

* Enter the wire resistivity (Ω·m), length (m), and cross-sectional area (m²).

Step 1: Enter Wire Parameters

Resistivity, \( \rho \) (Ω·m):

Example: 1.68e-8 Ω·m (Copper)

Wire Length, \( L \) (m):

Example: 100 m

Cross-Sectional Area, \( A \) (m²):

Example: 1e-6 m²
