Resistivity Calculator

Use our Resistivity Calculator to determine the electrical resistivity of various materials quickly and accurately. Enter the material type, length, and diameter of the conductor, and the tool will calculate its resistance or intrinsic resistivity. Perfect for electrical engineers, students, and hobbyists working on wiring, circuit design, or material analysis.

How Resistivity Works

The resistivity (ρ) of a material measures how strongly it opposes the flow of electric current. The resistance of a uniform conductor is calculated using:R = ρ × (L / A) where L is the conductor length and A its cross-sectional area (based on diameter). Knowing resistivity helps in choosing the right materials for wiring, power delivery, and electronic components.

Material Selection

Different materials have characteristic resistivities. For example, copper and aluminum are highly conductive, while nichrome and steel are more resistive. Our calculator automatically adjusts calculations based on the selected material, ensuring accurate results for practical applications.
