Easily determine the electrical resistance of Nichrome wire with our free online calculator. Input the wire's length and gauge (AWG) to get instant, accurate results for your heating elements, resistors, and other electrical applications. Understand how Nichrome's properties impact circuit design.
Formula:
The resistance (R) of Nichrome wire is calculated using its resistivity (ρ), length (L), and cross-sectional area (A):
R = ρ * (L / A)
Where:
- R = Resistance (Ohms, Ω)
- ρ = Resistivity of Nichrome (approx. 1.1 x 10-6 Ohm-meter at 20°C)
- L = Length of the wire (meters)
- A = Cross-sectional Area of the wire (square meters), derived from its diameter which is calculated from the AWG gauge.
