Inductance of Straight Wire & Electrode Calculator


A single, straight wire already has some inductance.  A straight wire, or electrode, typically has some inductance due to its unique shape. This may be significant when working with high frequencies (>10kHz) and low impedances (1 ohm).

Calculator for Inductance: Formulas and Equations:

L = K x [ ln (2l / a) – 0 .75]
