Nichrome Wire Calculator Online

The Nichrome Wire Calculator serves as a vital tool in determining the resistance of Nichrome wire. This calculator assists in obtaining the resistance value (in ohms, Ω) by utilizing the following formula:

Formula of Nichrome Wire Calculator

The formula employed by the Nichrome Wire Calculator is:

R = (ρ * L) / A

Where:

• R represents the resistance in ohms (Ω).
• ρ (rho) denotes the resistivity of the Nichrome wire material in ohm-meters (Ω·m).
• L signifies the length of the wire in meters (m).
• A represents the cross-sectional area of the wire in square meters (m²).

Example of Nichrome Wire Calculator

Suppose you have a Nichrome wire with a resistivity of 100 Ω·m, a length of 5 meters, and a cross-sectional area of 0.001 m². Plugging these values into the Calculator formula gives:

R = (100 * 5) / 0.001 = 500,000 Ω

This demonstrates how the calculator processes the inputs to derive the resistance value.
