Title: Eros Build - Resistor question
Post by: amritdesai on September 22, 2016, 06:55:00 AM

I seem to be missing two 470k ohm resistors in my kit (4703F). I am on page 67 of the manual and I have two remaining resistors left - Green, purple, black, orange, brown that are not measuring 470k ohm (see below). Also, I do not see these on the list of parts.

I just wanted to verify these are the incorrect parts before I bug Eileen? Can I go with something with a different value?

Thank you!

0.474MΩ = 474KΩ

AND
470 x 1% = 4.70
SO
470±1% = 465.3 - 474.7

THEREFORE a resistor that measures 0.474MΩ is a 470KΩ with 1% accuracy.

Awesome. That's why I asked!

Thank you Josh!

The first stripe is yellow, not green. Yellow is 4.

lol I went through the same thing during my Eros build.  I had to go through the parts list about 3 times before I got everything sorted.  Then, I still messed it up by putting a 47k resistor in a 470k spot.  Too many 47s  :o
