Weerstanden naar kleurcode E24 reeks
Deze weerstanden uit de E24-reeks hebben de twee eerste ringen voor het getal, de derde voor de vermenigvuldigingsfactor en de laatste (goudkleurige = 5%) ring voor de tolerantie van de weerstandwaarde.
In de tabellen zijn de kleurringen in alfabetische volgorde gerangschikt van bruin tot en met wit.
Verder is te zien dat de lagere waardes meer variaties kennen dan de hogere waardes. Uitleg van de kleurcode voor weerstanden.

Kleurcodering voor elektronica
De kleurcodering voor elektronica is een manier om met kleuren de waarde van elektronische componenten zoals weerstanden, condensatoren en spoelen aan te geven.
Kleurcodes op componenten dateren van ruim vóór de komst van de transistor. Het probleem dat zich voordeed was dat van gemonteerde componenten heel vaak de waarde niet af te lezen was omdat de bedrukte kant niet in het zicht was, maar bijvoorbeeld tegen het chassis of een andere component lag. Vooral bij reparaties was dat erg lastig. Men zocht naar een codeerwijze die aan alle zijden van de component goed af te lezen was, en als logische keuze kwamen ringen naar voren.
De kleuren zijn genormaliseerd in de norm IEC 60757. De woorden van het in de tabel getoonde ezelsbruggetje beginnen met dezelfde letters als de kleuren van de code en er is ook gedacht aan de tweede letter van bruin, geel en groen, en het hele woord grijs, zodat daar ook geen verwarring over bestaat. De kleuren rood t/m violet hebben trouwens dezelfde volgorde als de kleuren van de regenboog, dus als men die kent, heeft men wellicht geen ezelsbruggetje nodig. Lees verder Bericht ID 4197
