N\u00e4r man har tv\u00e5 likstr\u00f6mskablar i samma f\u00e4rg (t.ex. b\u00e5da r\u00f6da eller b\u00e5da vita), men den ena har en **svart linje l\u00e4ngs isoleringen**, s\u00e5 \u00e4r den svarta linjen d\u00e4r just f\u00f6r att **m\u00e4rka skillnad p\u00e5 plus och minus**.<\/p>\n
Det vanligaste \u00e4r:<\/p>\n
* **Kabeln utan markering** \u2192 anv\u00e4nds som **+ (positiv)**
\n* **Kabeln med svart linje** \u2192 anv\u00e4nds som **\u2013 (negativ)**<\/p>\n
\ud83d\udc49 Detta \u00e4r dock en **konvention** \u2013 det finns ingen absolut standard f\u00f6r just randiga DC-kablar, s\u00e5 man ska aldrig utg\u00e5 ifr\u00e5n det utan att m\u00e4ta.<\/p>\n
S\u00e5 f\u00f6r att vara helt s\u00e4ker g\u00f6r man s\u00e5 h\u00e4r:<\/p>\n
1. **F\u00f6lj kablarna till str\u00f6mk\u00e4llan** (batteri, n\u00e4taggregat, kontakt). Ofta \u00e4r plus tydligt markerad d\u00e4r.
\n2. **M\u00e4t med multimeter** \u2013 s\u00e4tt den p\u00e5 DC och m\u00e4t mot jord\/chassi eller direkt mellan kablarna. D\u00e5 ser du vilken som \u00e4r positiv och vilken som \u00e4r negativ.<\/p>\n
\u26a0\ufe0f Viktigt: Kopplar man fel polaritet i DC-system kan elektronik g\u00e5 s\u00f6nder direkt, s\u00e5 alltid dubbelkolla.<\/p>\n
