Resistor color code calculator helps determine the resistance value indicated by the colored band. You can use it for 3, 4, 5 and 6 band resistors. You can click the band in the color table to select a color for that band. The resistor visually shows your band color selection and displays the corresponding resistance value. It will help you configure your electronics. How to use the resistance color code calculator - Please select the number of band colors first. - Select the color of the band by clicking on the corresponding box in the color chart. - The corresponding resistance value and the tolerance of the resistance are displayed.
