13.019 Could someone please post a resistor color code chart?

    
Color   Digit   Multiplier (when 3rd band)  Example

Black     0       x1              --  Red Red Black =         22 Ohms
Brown     1       x10             --  Blue Grey Brown =      680 Ohms
Red       2       x100            --  Orange White Red =    3900 Ohms
Orange    3       x1000           --  Yellow Violet Orange = 47k Ohms
Yellow    4       x10000          --  Red Green Yellow =    250k Ohms
Green     5       x100000         --  Orange Orange Green = 3.3M Ohms
Blue      6       x1000000        --  Red Yellow Blue =      24M Ohms
Violet    7       x10000000       --  ...
Grey      8       x100000000
White     9       x1000000000

Gold      -       x 0.1           -- Brown Brown Gold =      1.1 Ohms
Silver    -       x 0.01          -- Orange White Silver =  0.39 Ohms

Tolerance (4th band)

Red is           <5% (courtesy of Edhel Iaur)
Gold is           5%
Silver is        10%
no color is      20%

Example: Grey Red Orange Gold      is 82k Ohms  +/- 5%
Example: Brown Black Green Silver  is  1M Ohms  +/- 10%

Note: carbon resistors almost always err on the high side.
