Learning Aid - resistors

[Enzo]

I found this in Embedded Electronics Journal, and it may help you learn the resistor color codes.

Graphical Resistance Calculator

Set the colors on the resistor image and it tells you the resistance.

Very simple.

There are dozens of mnemonics for remembering the colour code, most of them un-PC or even unprintable.

thanks for the link.

Now if I could just tell what color the bands on the resistors really are? The bands mostly all look blurry and sort of mud colored to my eyes these days.

best,

Yep there are lots of memory aids. I Have hired and fired technicians over the years, and at interview, one of the first things I do is check the general knowledge, "Here, read this color code." I had a guy once looked at the resistor I handed him them started reciting aloud, "Our bad boys..."

When A was a kid, I just learned them, I never had a mnemonic. I remember yellow/purple was the first pair I managed to internalize. I knew that was 47 even when I couldn;t quite remember what blue/gray was. And it didn;t take long for the others to fill in, until one day I just knew them.

But I did have - aside from the chart in a book - a little cardboard resistor calculator things that worked just like this thing I have linked to above. You turned three little cardboard wheels so the right color appeared in an opening in a picture of a resistor. Then numbers appeared in other openings. I used to look up the ones I was not sure of. Like green. What is that darn green anyway?

...ours (USN) ended with "...Violet Gives Willingly..." and the tolerances were: "...Get Some Now..." for Gold(5%), Silver(10%), None(20%).

...not PC, but VERY rememberable, for sure!

Well, according to what you and Steve said, Sigmund Freud was definitely right !!
