Line Inductance Calculator

Line Inductance Calculator

Calculate the total inductance using: $$ L_{\text{total}} = \frac{\mu_0\,L}{\pi}\ln\!\left(\frac{D}{r}\right) $$

* Enter the line length, conductor spacing, and conductor radius in millimeters (mm). They are converted to meters automatically, and the result is displayed in microhenries (µH).

Step 1: Enter Parameters

e.g., 1000 mm (1 m)

e.g., 100 mm

e.g., 5 mm

Formula: $$ L_{\text{total}} = \frac{\mu_0\,L}{\pi}\ln\!\left(\frac{D}{r}\right) $$
with \(L\), \(D\), and \(r\) converted to meters and \(\mu_0 = 4\pi \times 10^{-7}\) H/m.
