On the HacDC mailing list, we’ve been having a discussion about Wolfram|Alpha and some of the amazing things it can do (and some of the controversy already surrounding it). Here ‘s the return on a query for resistor values.

If you’re a yubnub user you could also find useful the command resistor. As:
resistor 4k7 -tol 5
It takes you to http://www.okaphone.nl/calc/resistor.shtml?ohm=4k7&tol=5
It also gives you the nearest standard resistor value.
There does seem to be a bit of controversy, but I am still eager to try it out.
Whoa, whoa, whoa…. major terms of service violation here.
It’s strange how it can find a resistor given the colours, but how do you go the other way?
I’ve tried “25k”, “25k resistor”, “25k resistor colours” but it can’t work it out. I guess the wolfram programmers haven’t added this kind of query yet.
You would need to search for 25k ohm resistor etc
