INDUCTANCE

2 Parallel Plates Coaxial Cylinders  Wire Loop

 

The formulas on this page allow one to calculate the inductance for certain given geometries.  More complex problems typically require one to model the geometry and solve using Finite Element Analysis.  The viewer should note that the permeability has been set to that of free space for these formulas since that is typically the most common scenario in calculating the inductance of a transmission line, cable, etc.

Other inductance formulas can also be found in the following references:
