The first three bands are colored:
Black = 0 Brown = 1 Red = 2 Orange = 3 Yellow = 4
Green = 5 Blue = 6 Violet = 7 Gray = 8 White = 9
The fourth band (if any) is colored:
Gold = 5%, Silver = 10%, (NONE = 20%)
To use this calculator simply select the color for each band from the drop down menus. Click "display value" for the result. To re-calculate, simply re-select any one of the drop down color bands, and continue...
The color bands one and two are NUMBERS BLACK = 0, BROWN = 1 etc. (see colors above). EXAMPLE: BROWN, BLACK would be 10, while BLACK, BROWN is 1 (drop the 0). The third band is a (X) multiplier of the first 2 bands; Black = 1, Brown = 10, Red = 100, Orange = 10K, Yellow = 100K, Green = 1M, Blue = 10M. EXAMPLE: Brown, Black, Blue = 10M Ohms. NOTE: The Black band is not used above 9 Ohms, Brown is the first band for all resistors with a value for 10 - 100 - 1000, 10,000 etc. EXAMPLE: Brown, Black, Red = 1000 Ohms not Black, Brown, Orange as this calculator will display as 1000 Ohms.
The fourth band is a TOLERANCE band. There are only two possible bands here: Silver (10%) and Gold (5%) if there is no band the resistor is 20% tolerance. EXAMPLE: A 1000 Ohm resistor with a 20% tolerance could be an 900 Ohm or 1100 Ohm value and still be within TOLERANCE. NOTE: Silver is most common in modern supply as we know it. NOTE: Some Japanese resistors have shown a band of Black (20%) or a band of White (2%). However these are rare and this calculator does not share the values.
