Resistor Color Coding Scheme

There are three types of resistor color coding. They have different number of color bands and hence provide different information. This is illustrated by the next table. You can calculate the value of an unknown resistor by entering its color code in the fields below the table.
 

6-band color code 3 digits, multiplier, tolerance, thermal coefficient	5-band color code  3 digits, multiplier, tolerance	4-band color code  2 digits, multiplier, tolerance
Enter all the color bands.	Select None for field 6.	Select None for fields 3 and 6.

And finally here is the complete color codes table. The band number that contains the given value is shown in braces [ ] and the table is easy to use by itself.
