So according to the formula the resistance will be: 16 * 100 = 1600 Ohms or 1.6K Ohms with 5% tolerance. Note that twelve different colors are used as codes and each color band indicates a decimal value associated with it. Silver represents a 10 tolerance, while Brown represents a 1 tolerance.

The color gold implies a tolerance rating of 5. The Resistor Color Code Calculator identifies the value and tolerance of a color coded resistor given its bands colors. The last bands of a 4- or 5-band resistor are used to indicate the resistors tolerance value.

Let’s take an example of a 4-band resistor with the colors given in the above image (brown, blue, red and gold). Look for color in a chart with value 1, then its your 3rd color band (say brown). ‘ d’ represents the 4 th significant digit, which is the fourth band color of resistor and this is the tolerance value. ‘ c’ represents the 3 rd significant digit, which is the third band color of resistor and this is the multiplier value. ‘ b’ represents the 2 nd significant digit, which is the second band color of resistor. Here, black is 1, brown is 10, red is 100 and so on. The third color band is the multiplier of the first 2 bands. ‘ a’ represents the 1 st significant digit, which is the first band color of resistor. Resistance As can be seen in the above 4 Band Resistor Color Codes chart, the first two color bands have values of brown 1, red 2, orange 3 and so on.

Just have a look to the resistor color code chart below and see the calculations, how the resistance value is calculated according to this chart.Ĭalculating resistance for a 4-band resistor 1 Brown 2 Red 3 Orange 4 Yellow 5 Green 6 Blue 7 Violet 8 Gray 9 White. To calculate the resistance of a resistor, you can select the appropriate color bands in the above resistor color code calculator. For example, the value of resistance for shown three band resistor color code ( Brown, Black and Red) according to the table would be: 1. A resistor is identified by its pattern of color of bands.
