Resistors are electrical components used very frequently in electrical or electronic circuits. They are used to provide resistance to the flow of electricity. That resistance is measured in Ohms[Ω]. An Ohm is a measure of, well, electrical resistance. The unit was named after Georg Ohm, a 19th century German Physicist who gave us Ohm's Law, among other things. 1Ω really isn't much resistance at all, so in electronics, more often we talk in terms of kiloohms or megaohms. Resistors come in a wide range of resistances, and since most are very small, simply printing the resistance on them, something like 470KΩ, just isn't workable. I wouldn't have been able to read them even when my eyes were young. Instead they are marked by a series of colored bands. Each color stands for a number, or a power of ten. The colors are Black = 0 or 100, Brown = 1 or 101, Red = 2 or 102, Orange = 3 or 103, Yellow = 4 or 104, Green = 5 or 105, Blue = 6 or 106, Violet = 7 or 107, Gray = 8 or 108, White = 9 or 109.

Now, it is easy to see that this racy mnemonic also taught something else to the overwhelmingly male technology students it was aimed at. It made the violent crime of rape out to be something frivolous, while at the same time it divided women between "good" and "bad" depending on if force was necessary to have sex with them. It also was, all by itself, another barrier women had to overcome to pursue careers in a number of well-paying, male dominated, fields.
Years later, I found there was an even worst version of this mnemonic. Perhaps I was shielded from it because it combined racism with the misogyny. This is from a European electronics manual:
I wasn't shielded from discrimination as I developed my technology career. In this version, "our" applied both to the men who needed to remember this bit of technological trivia, and the "young girls," and it went without saying that both were understood to be "white." This racist version may indeed be more popular in Europe. The Daily Mail had this report about a teacher using it lately:
THE RESISTOR COLOUR CODE Here is an industry-standard mnemonic e-mailed by Bill Woods for recalling the order and value of colour-markings on resistors. Although a politically/socially dubious phrase, it has nevertheless served to teach budding electronics engineers the code successfully for many years.
"Black Boys Rape Our Young Girls, But Violet Gives Willingly."
Hersey's version of this little ditty packs quite a few "collateral" social lessons into this memory exercise. In addition to the trivialization of rape contained in all versions, and the racist element added to some versions, his version promotes the view that women or girls who are raped, are raped because they want it, after all, "virgins go without."
Teacher who taught pupil racist 'rape' rhyme so he
could remember lesson is guilty of misconduct
25 February 2011
A supply teacher who taught a racist rhyme to a pupil - which included the vile phrase 'Black Boys Rape Our Young Girls' - has been found guilty of professional misconduct.
Teacher James Hersey of Hove, East Sussex, holding a circuitboard: He claims the rhyme he was taught in the 1950shelps to remember a colour coding system for resistors
James Hersey, 68, taught the shocking mnemonic to a 16-year-old boy who was revising a wiring colour coding system for electronic resistors.
He taught the boy the ditty: 'Black Boys Rape Our Young Girls, But Virgins Go Without.' Each word represents the first letter of the colours in the code which are; black, brown, red, orange, yellow, green, blue, violet, grey and white. More...
Christine Blasey Ford's heartfelt testimony before the Senate Judiciary Committee Hearing on the nomination of Judge Brett Kavanaugh to the Supreme Court showed the lifelong damage that can be caused by teenage acts of sexual violence that are encouraged and trivialized by teaching methods such as this one. I'm not sure if this mnemonic is still used anywhere else in the past seven years. I certainly hope not. Clearly, it's time has passed.
