Wire Resistance Calculator
This CalcTown calculator calculates the resistance of a simple wire given the resistivity and dimensions of the wire.
Wire Resistance Calculator
where
ρ: Resistivity constant of the material
L: Length of the wire
A: Cross sectional area of the wire
R: Resistance
Here is a list of resistivity values for common materials.
