Do not tie them together. If the insulation is a dark color, the stripe or dash is more likely to be white. When wiring a new ceiling light, or any ceiling fixture, it is important to identify the positive and negative (or neutral) wires. Basic speaker wire—not the RCA or Optical/TOSLINK kind—has only two parts to deal with on each end, a positive (+) and a negative (-). Electrical polarity is a term used throughout industries and fields that involve electricity.There are two types of poles: positive (+) and negative (−). Testing of polarity in alternating current system can be done by an instrument such as a dual-trace oscilloscope that can identify when two points have instantaneously similar voltages, or by measurement between terminals with a voltmeter. standard car audio convention … 1 1. comments. If the speaker is working … so which is negative, and which is positive? If a speaker wire doesn't have a two-tone color scheme, look for a single stripe or dashed lines (these usually indicate the positive end) along one of the sides. Very thin, lean-sounding bass, poor subwoofer performance, or both, A general sense that the system just doesn't sound right. For example, a set of loudspeakers used for stereo music reproduction will have all device terminals and wiring marked to ensure the same instantaneous polarity, so that the resulting sound produced by each speaker element is in the same phase and add correctly at the listener's ear. Reverse battery or DC polarity protection. So, take your time to make sure that all speakers are in-phase: positive-to-positive (red-to-red) and negative-to-negative (black-to-black). Wire markings, especially for electronic equipment, are typically colour coded to designate the positive and negative polarity. https://en.wikipedia.org/w/index.php?title=Electrical_polarity&oldid=1002265127, Short description is different from Wikidata, Articles needing additional references from December 2018, All articles needing additional references, Creative Commons Attribution-ShareAlike License, This page was last edited on 23 January 2021, at 16:36.
