At such voltage, a 1 loss will occur at zero.3 ohms or extra of inductive reactance. Consequently, to keep audible (up to twenty,000 hz) losses beneath 1, the entire inductance inside the cabling should be stored under approximately 2 μh.

Regular lamp wire has a capacitance of 10–20 pf in keeping with foot, plus some picofarads of stray capacitance, so a 50-foot run (one hundred total feet of conductor) could have much less than 1 percentage capacitive loss in the audible range. Some premium speaker cables have better capacitance with a purpose to have lower inductance; 100–300 pf is traditional, in which case the capacitive loss will exceed 1 percentage for runs longer than approximately 5 feet (10 toes of conductor).

Maximum client applications use two conductor twine. A commonplace rule of thumb is that the resistance of the speaker wire should no longer exceed five percent of the rated impedance of the machine. The desk under shows encouraged lengths based totally on this guiding principle:.

Speaker cord is a passive electrical factor defined by using its electrical impedance, z. The impedance may be broken up into 3 properties which decide its overall performance: the actual part of the impedance, or the resistance, and the two imaginary components of the impedance: capacitance and inductance. The correct speaker cord has no resistance, capacitance, or inductance. The shorter and thicker a wire is, the lower is its resistance, as the electric resistance of a cord is proportional to its period and inversely proportional to its move-sectional vicinity (besides superconductors). The cord's resistance has the greatest effect on its performance.[3][4] the capacitance and inductance of the cord have less effect due to the fact they are insignificant relative to the capacitance and inductance of the loudspeaker. As long as speaker wire resistance is kept to much less than five percentage of the speaker's impedance, the conductor can be adequate for domestic use.[4].

Silver has a barely lower resistivity than copper, which permits a thinner cord to have the equal resistance. Silver is luxurious, so a copper cord with the equal resistance costs considerably much less. Silver tarnishes to form a thin surface layer of silver sulfide.
