17K value doesn’t existi in any tolerance http://wps.prenhall.com/wps/media/objects/12685/12990452/AppendixA_StandardResistorValues.pdf … So no such standard color code 🙂
It was fun to see how such easy question can mislead so many people!

That’s what happens when people are using Google rather than EE experience to answer the question.

No, that happens when weasel tactics are applied. As the latin alphabet is not limited to words found in a dictionary, the color codes are not limited to E-series. And there are 17k resistors: http://www.alibaba.com/showroom/17k-ohm-resistor.html

please do not act like kids 🙂 the purpose of this quiz is to be fun and people who participate to learn new stuff by searching the answers, friendly advice – never trust what is written in Alibaba, they do not control traders there you will see quotes for quad core processors in range: $0.01-$100 if you believe that they sell 17K resistor (probably will ship you 16.9K) you should also believe that you can buy processor for $0.01 🙂

Standard resistor values follow E192 series, don’t they?

In the name of a good-natured debate as well as personal education… Isn’t a 16.9 ohm resistor with even 1% tolerance just as likely to be 16.8k or 17k ohms? If it’s 5 or 10% tolerance, the third digit isn’t even mathematically significant. Or am I misunderstanding tolerance?
And does EE experience really help you memorize the entire table of standard resistor values? Seems like a waste of valuable neurons when it can be looked up so easily.
Finally, gramatically, “what is the color code for 17k ohm resistor?” can more easily be interpreted as “if a 17k ohm resistor were to exist, then what would its color code be?” than “Does a 17k ohm resistor exist, and if so what is its color code?” Good “trick questions” have subtle clues that wary readers can pick up on, like “what is the color code for a standard 17k ohm resistor?”

Is digikey unreliable too? They may not stock them, but they do exist.

I agree. “what is the color code for 17k ohm resistor” definitely sounds like “if a 17k ohm resistor were to exist, then what would its color code be?” The wording is confusing!
Jan 29, 2016 @ 01:15:55
Then the question had to be: “What is STANDARD color code….”
Jan 29, 2016 @ 01:23:59
Right. If they had included that extra word then it would have been a valid trick question. As it stands I think they tricked themselves. 🙂

The key word here is “standard”. 17k doesn’t exist as a standard value, but you can find resistors of pretty much any oddball value – these will almost always be 1% precision resistors, since the only true need for an oddball value requires it to be that precise; otherwise a standard value could be used.
