• I hope I don't get in trouble for this but as I am a R&D electronic tech and having got my education from Uncle Sugar here is a little ditty that might help,

  Bad Boys Raped Our Young Girls But Violet Gave Willingly, Get Some Now

  As you can tell with a little thought that is the resister color code including the tolerence bands. If I get enough positive feedback I'll make a pretty picture of it and post it for ya

• There is a typo in the example.
  It should be:
  Resistor value = 20 x 1000 = 20K ohms

• This is what I did - I labeled each resistor bin/drawer with the color code. I have done this for several places that I've consulted.

  This is an example: USBmicro resistor labels from USBmicro

  The small drawer labels are available from that site as color pdf files.

• I'm new to this but his little chart on the pdf says brown is 1 and not 0. Wouldn't that make his example on the pdf, red brown, be 21 and not 20?

• Hey all, thanks for checking my work. I fixed both typos, and updated the files on my site. D'oh!

• "Unlabelled resistors"? You mean somebody scraped the stripes off?

  With a little bit of practice, you don't need to interpret the resistor color code. You just look at it and say "Oh, that's a 6.8K resistor". In fact, I couldn't tell you what the colors for that would be, but I know one when I see one.

• RannFox - you won't get in trouble and i'm not going to delete your comment - but here's something to think about... all these new people learning electronics could learn something better than this offensive mnemonic - i realize it's still said and taught all the time, but we don't need to continue this. if you look at the history of this mnemonic it's been pretty awful.

• Rannfox, I learned that one from an old Navy electronics guy. And I stll use it today. I did hear one that did not involve sex, but who can remember something like that?

• again - why don't we use this opportunity to kill a bad mnemonic.

• In the multiplier column, black's value should be 1 and not zero. I think it also makes it a bit clearer if you were to label the multipliers via factors of 10.
