Resistor Color Code Calculator

This resistor calculator requires the use of Javascript enabled and capable browsers. For operational and other information, and for those unable to use the calculator because of browser limitations, there is a resistor color code chart below the calculator and additional information below the table. For those in the electronics business that are color blind (as I am), working with resistors and color coded capacitors can be difficult. This table names (as well as shows) the colors and the values. To use the calculator, select a value from the vertical group of Color Band 1, from Color Band 2 and from Color Band 3. Immediately to the left of the Calculate Values button below the three bands, there are three boxes that upon selection of a color from the bands, an identifying number and color will correspond in appearance. After selecting a value from all three bands, click on Calculate Values and the resistor's value is calculated and will appear as well as a text representation of the three bands. This calculator does not consider the 4th Band, tolerance, since it would not change the calculation. You may change a value by again clicking on the band values from any of the three bands but be sure to click on Calculate Values after each selection to update the correct information of resistor value and color band text representation.
