:Red black yellow would be 200000 ohms, or 200kΩ (200 kilohms). Red-black is 20, and yellow is basically adding 4 zeroes to that. [[User:SuperSupermario24|<span style="color: #c21aff;">Just some random derp</span>]] 17:56, 16 November 2015 (UTC)

i don't know how to add the omega sign for the units of the resistor in the transcript. i'll leave that to someone more skilled than myself Beardmcbeardson (talk) 05:26, 16 November 2015 (UTC)

Just copy-and-paste! -N00b 108.162.214.77 (talk) (please sign your comments with ~~~~)

Or find the 'omega' symbol in Windows Character Map. RAGBRAIvet (talk) 08:37, 16 November 2015 (UTC)

To be exact, a 24Ω resistor would be red, yellow, black; 240Ω would be red, yellow, brown, and so on, along a well-defined sequence. Red, yellow on its own would be missing the final "scaling" colour. Gearóid (talk) 08:54, 16 November 2015 (UTC)

According to https://en.wikipedia.org/wiki/Electronic_color_code, a "black red black red black" resistor shoud be 2kΩ, not 24Ω ... -- Oicebot 162.158.252.119 09:30, 16 November 2015 (UTC)

The fourth band on a resister is usually the multiplier (the value gets multiplied by 10 to a power according to the colour); it's the fifth that indicates tolerance sbutler87

The resisteors that I have at hand are coloured the way I remember, Three bands of 'spectrum' colours (including black at zero, brown for 1, leading through the spectrum red to violet until grey at 8 and white at 9), the first two are literal, the third the power of magnitude to adjust up, and a fourth band (metalic silver/gold, to aid identification of the direction to read) as tolerance.
I know there's variations, and zero ohm (or effectively so) links are a single black band, but that's all I've ever needed to know, in my time. (When I don't put something across mulimeter probes, just to make sure...) 162.158.152.221 11:57, 16 November 2015 (UTC)
