Re: Resistors, electronics guys help me out, simple question:

Just out of curiosity, why is it that the industry continures to persist in using coloured rings as identifiers?

It is easy to read.
And because it is an Industry, so we use on a daily basis and it far from bothered by it.

It would seem that a stamping of say "50k-10%-1/4W" would make life much easier. This should be possible (given even the small size of an 1/8th watt resistor) as wire gauge/temp ratings, etc are fairly easy to read, even on 22 gauge. Caps values are stamped, the very small ones included. OK, agreed, you might need a bit of magnification for some.

Always wondered this. Anybody know the answer?

Here's the real reason:

Because the color bands go all the way around the part, the part can be used or inserted into a circuit board (either by hand or by machine) without worrying if the value is going to show or not. For machines especially, it would be impossible.

Also because if the ink sputters a bit, you're not left scratching your head going "now is that a 7 or a 1?"
