    Hello,

    I have resistors. Purchased. :D

    Now, I heard that it can be identified by its colors. nOW, im confusing!!!

    pls help!!!

    1 resistor colored=orange,black, and brown
    2 resistor colored=red, black, and brown
    3 resistor colored= brown, purple,and yellow green.

    Um, help?

    resistors that i have purchased is 470Ω,1kΩ,10k.Ω

    Thanks!

    Orange, Black and brown should be 300 but are you sure it is not brown, black and orange, or 10,000?
    Only thing I can see. :cool:

    If you google resistor color code You will find a lot tables to decode the color code. Also some online calculators. Find the one that you like best. And stick to that

    Bad Boys Ravished Our Young Girls, But Violet Gives Willingly.

    0 - Black
    1 - Brown
    2 - Red
    3 - Orange
    4 - Yellow
    5 - Green
    6 - Blue
    7 - Violet
    8 - Grey
    9 - White

    This simple mneumonic will help you remember the color code, it was old when I was new.

    Most (but not all) resistors have 3 rings to identify what the resistor is. 1st color, 1st value, second color same, 3rd color is the number of zeros after the first two digits.

    So Orange Orange Orange will be 33000Ω

    The is a fourth ring, but it is usually gold or silver. Gold is 5% tolerance, silver is 10%. So 33000Ω ± 5%, or 33000Ω ± 1650Ω

    and if you *have a smartphone with android just download the app

    Electrodroid, awesome stuff in there.


    the 1st option is just what you need you get the colors you have on the program and it will tell you the value of the resistor.

    or the other way around too (input value, output colors)

    Best regards and have fun ;)

    I always use a good digital Ohm meter to determine what the colors are.

    He might not get that...

    I'm pretty sure kids in the Philippines don't generally have smartphones ;)
    Thats an american thing.

    Lightfire, the order of the colors matters, In the electronics cheat sheet thread there is a picture with the colors and meanings that you can print off and use, I have one hanging on my wall.

    You can also download programs to use on your PC. But be careful then downloading stuff. So you do not get virus.

    Obviously you are remembering it the way I originally learned it with a few different words in there. :eek:

    All you missed this, I think.

    You have an excellent source for the color code at the top of this forum. Go to top of forum and open Vol. V - Reference. Click on "Color Code" (Table of contents, left of page.) Open the chapter then click on color codes. Very well put together explanation and examples. :rolleyes:

    true true :p

    but it can also help other ppl out there too!

    (and i am not american, and also own one for 75€ and some tweaks made hehe, anything based on linux SO can be exchanged to android +- easily)

    Most people use anti-virus and anti-spyware software to avoid problems.
    My internet provider supplies good software for free.

    Basically how I remember it too, your version is a bit less violent then I was taught.

    You can also take on "Get Some Now" for the tolerance:

    Get: Gold 5%
    Some: Silver 10%
    Now: None 20%

    Bad Boys Ravished Our Young Girls, But Violet Gives Willingly. Get Some Now.

    Note: Despite many years in the industry and countless Google searches I have yet to find this Violet girl!

    The one I learned was probably invented by some child--It's a lot milder than Violet's :D

    It sounds really stupid, I know, but it's how I learned :p:D

    Usually, resistors have at least 4 color bands; the last one being gold (5%) or silver (10%) to indicate the tolerance.

    A long time ago, resistors had only 3 color bands, and the tolerance was 20%. Even longer ago, tolerances were 50%.

    Here is a link to a nice graphical resistor color decoder page:
    http://samengstrom.com/24614782/en/read/4_Band_Resistor_Color_Codes
    That page is for 4-band color codes. There are also decoders for 5- and 6-band codes, accessible by clicking the links on the upper left of the page.

    Wahhh! Almost all of my classmates had smartphones. If not smartphones, yea, laptop. :D But, I'm not belong to those. I'm not fond of those gadgets. :)

    Hi, Catapult :)

    As you grow up you will see the need more and more for "those gadgets." They are beginning to play a major role in the world, and make your life significantly easier. I personally do not have a smartphone, but I do have a laptop. I honestly don't know what I would do without it :D
