Above you see the applet for calculating electronic color codes to resistance values in Ω and the other way round.
* By clicking with the left mousebutton on one of the six color bands, you traverse forward through all possible colors. With the right mousebutton you can go backwards through all colors.
* You can specify a resistance value in the text field and press Enter - then the matching color bands are calculated and displayed. Note that your entered value is rounded to the next valid resistance value. It is not possible to specify a tolerance or temperature coefficient value.
