In a four band resistor which is the most common the first two bands also represent the first two significant digits. Im not going to go into detail about the temperature coefficient in this post but the chart can help if you run into one of these.

Resistor Color Code
If your answer is yes then this tool is specifically designed for you.
One band resistor color code. The first band was given by the body color the second band by the color of one end of the resistor and the multiplier by a dot or band around the middle of the resistor. Some resistors have the color bands grouped together andor close to one end. More online conversion calculators at digi key.
To use this tool simply click on a particular color and number and watch how the actual bands on the resistor illustration change. To calculate the resistance of four band resistor the below color code chart is considered. The body end dot or body tip spot system was used for cylindrical composition resistors sometimes still found in very old equipment.
Resistor values are often indicated with color codes. There is a special scenario in case of 5 band resistor color code resistor where the forth strip is gold or silverin this case the first two bands shows the fist two significant digits third one is for multiplier 4th one is for tolerance and 5th one is for temperature coefficient same is in six band resistor color code resistor. The coding is defined in the international standard iec 60062.
6 band resistor color code. You now know that zero ohm resistors exist. Since no tolerance band is available the tolerance will always be 20.
How does the resistor color code work. Practically all leaded resistors with a power rating up to one watt are marked with color bands. Resistors come in a range of tolerances but the two most common are the e12 and the e24 series.
Hold the resistor with the silver or gold band to the right and read the resistor from the left to. Hold the resistor with the closely grouped bands to your left and read the resistor from the left to the right. The picture below is a color code chart for 6 band resistors.
In a three band resistor the first two bands represent the first two significant digits followed by one band for the multiplier. 2 with 5 and 10 resistors the procedure is simple. The resistor color code calculator decodes and identifies a value and tolerance of 4 band wire wound resistors.
The four band resistor indicates the first digit for the 1 st band second digit for the 2 nd band third digit for 3 rd band multiplier or power of 10 and the fourth digit for 4 th band represent tolerance of 5 10 and 20. The five and six band resistor colour code is more commonly associated with the high precision 1 and 2 film types while the common garden variety 5 and 10 general purpose types tend to use the four band resistor colour code. Our resistor color code calculator is a handy tool for reading carbon composition resistors whether its a 4 band 5 band or 6 band type.
This standard describes the marking codes for resistors and capacitors.
