Resistor Color Code
Are you having trouble reading resistor color codes? If your answer is yes, then this tool is specifically designed for you! Our Resistor Color Code Calculator is a handy tool for reading carbon-composition resistors 4-band type.
To use this tool, simply choose on a particular color and number and watch how the actual bands on the resistor illustration change. The resistance value is displayed in result together with the tolerance.
Resistor Band Colors
Calculation Equation is
Total Resistance =[ firstColor + secondColor*10 + (10**thirdColor)] +- tolerance
