  • Resistor values

    Bought a pack of asorted resistors today.
    It says there are some 1K resistors in it but I'm dammed if I can find these given the crap colour code table with them.
    These are 4 band ones 1/4W 5%
    other values are 10R, 22R, 47R, 100R, 220R, 470R, 1K, 2K2, 4K7, 10K, 22K, 47K, 100K, 220K, 470K, 1MO

    Could some kind soul give me the colours of the 1K ones.
    I need two for a job tomorrow.

    Ta.

      brown black red for 1k.
      I seldom do anything within the scope of logical reason and calculated cost/benefit, etc- I'm following my passion-

        Do you have a multimeter? Just measure them with that. Dont even need yer reading glasses !

          brown black red

          or

          you can use two - red black reds in parallel if you screw up the other ones!

          It is true, there is nothing free about freedom, don't be so quick to give it away.

            Just remember this.................

            Bad---------black----0

            Boys--------brown----1

            Rape--------red------2

            Only--------orange---3

            Young-------yellow---4

            Girls-------green----5

            But---------blue-----6

            Violet------purple---7

            Gives-------gray ----8

            Willingly---white----9

            First two colors are numbers, third band is the "multiplier" or number of zeros. So it's brown-black-red for 1K.

            Learned this when I was 10 years old. Still looking to meet Violet!

              There is a saying that helps you remember the color code.

              Bad boys rape our young girls but vilot gives willingly.

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

                Thanks guys,
                Got thrown by looking for 4 bands, found them now.

                BTW all the Violet'sI have know have had a high resistance

                  My high school science teacher taught me that about 10 years ago. He told the class, "Listen up, I'm only saying this once...."

                  I don't have a need to size resistors very often, so long periods of time go by where I don't think about it at all. But when the time DOES come, I NEVER forget it. It's cool to see many others know it too.

                      Pretty cool to see we went to different schools together. I learned the same rhyme about thirty-one or so years ago.

                        As an EE, this color code was one of the very first things I ever learned, and I have often wondered since why it has not become more commonplace outside the electronics field. I use it whenever possible to mark numbered things that need to be easily identified. Makes a lot of sense to associate a color with a number. How about using a brown wire for your #1 spark plug wire, red for #2 etc.

                          FYI, the "R" and "K" are decimal point placeholders:

                          22R = 22.
                          100R = 100.

                          4K7 = 4.7 Kohms or 4700
                          1M0 = 1.0 Megohms

                          for 1% resistors they would have another significant digit like these:

                          47R5 = 47.5 ohm

                          4K75 = 4.75 Kohms or 4750

                          etc.

                          SMT parts vary but when they're small enough, you don't have to worry about values anymore 'cause they ain't marked Den

                              Believe it or not, there is a code on even a 603 sice SMT resistor, at least on ours.

                              I have not looked at a 402 size.

                              Its the *&^$$%$#$# capacitors that are unmarked....at any size. The resistors you have a much better chance of measuring with common meters, but they are marked...go figure.

                              Most DMM capacitance ranges fail at low values.
