Wire Inductance

Wire inductance calculator based on formulas from: Rosa, E.B. (1908). "The self and mutual inductances of linear conductors". Bulletin of the Bureau of Standards.

Important: These equations apply only to an isolated round wire with return path at infinity (grounds or other wires far away).


Wire inductance formula DC
Wire inductance formula AC
Distance units: 

Wire Length, l  
Diameter, 2r  
DC Inductance, Ldc nH
AC Inductance, Lac nH
