[QUOTE="marantz123, post: 916954, member: 16849"] Any conductor with its inherent resistance, and loaded with a frequency will exhibit reactive values XL and XC due to its inherent inductive and capacitive values. The 0.05mH measurement will surely exist...it must...because the conductor has been subjected to required test conditions to achieve this. What Hz was the test app running at ? In a nutshell...XL = 2Pi FL or/and XC = 1/(2Pi FC). A massive coil of speaker wire ( i.e increasing the DC resistance "real" value & the resultant reactive value), coiled well enough will impede the high Hz response...according to the mathematics....whether this is audible will also depend on the strength of the inductor, and how much is needed for an audible change. If you have consistent Hz (50Hz AC) then the XL value will be consistent..creating the constant required for a sustained heating effect, keeping in mind that its largely the DC resistance that causes the heating effect, because electrical energy can only dissipate in a pure/real resistance....how much again depends on the mathematics. With the dynamics of an audio music programme signal, where the real value is favourably kept to a minimum and X is not sustained/consistent, due to a dynamic Hz heating is not pronounced. [/QUOTE]
