Contact surface of a loose connector has both contact resistance and small inductance, and inductance depends on distribution of true contact. Contact resistance and inductance was measured by time-domain reflectometry (TDR) for seven contact distribution models. Resistance was approximately constant, while inductance changed more than double depending on the distribution model. Approximate calculation of current path length showed good agreement with tendency of inductance for contact point distribution models.
