Rectangular Conductor Resistance Calculator

Calculates the dc Resistance of a single rectangular cross section strip (or track/trace) of common conducting materials using the equation below.

Enter the length of the conductor:   cm
Enter the width of the conductor:   mm
Enter the thickness of the conductor:   mm
Resistivity (ρ):   x 10-8 Ω.m
d.c. Resistance:    Ω

Note: To use different values for the Resistivity, select Enter Data in the Conductor Material selection text box and then enter the required values in the box highlighted in amber.

The dc resistance of a conductor is calculated using the equation:-

[Equation for Rdc]


ρ is the resistivity of the conductor in Ω.m

l is the Length in metres

A is the Cross-sectional area in metres

The values for ρ are from CRC Handbook of Chemistry and Physics 1st Student Edition 1998 page F-88 and are for high purity elements at 20°C.
