Electrical systems are extremely complex structures. In order not to damage the devices, direct current must always be passed through and many interfaces are used for this. One of these interfaces is the resistor. In its broadest definition, resistance controls electrical current. Of course, this device has a separate resistance value depending on the system in which it is used. This value is represented by resistor color codes.
Since the resistance value has an extremely wide range, number of resistor color codes it’s just as much. Professionals now understand what this value is once they see the color, but if you’re a beginner, resistor color codes can be extremely confusing. Fortunately, there are some tools you can use for the calculation process. Bride What are color codes of resistors, how to calculate? Let’s see all the details.
What is electrical resistance?

Electrical resistance refers to the force that the electrical system exerts against the current. Also in the system The interface name used for this purpose is also the resistor. The unit of resistance is the ohm and is abbreviated with the omega symbol Ω. The resistance value can be millions of ohms. The resistance value is indicated by the resistance codes.
What are resistor color codes?

The value of the resistance interface used to control the current in the electrical system is displayed. The colors on the bands are the color codes of the resistor. Resistance color codes; It consists of the colors black, brown, orange, yellow, green, blue, purple, gray, white, gold and silver. Resistor color codes are displayed on systems consisting of 3, 4, 5 and 6 bands.
Resistor color codes are accepted internationally It is determined according to the IEC 60062 standard. In addition to standard belt systems, military systems also have a belt to demonstrate reliability. The single black band indicates 0 ohms. The 4th band of the old 5 band resistors can be silver or gold color. In high voltage resistors, yellow and gray colors can be used instead of gold and silver.
Resistance color codes according to the number of bands:

- In the 3-color band, two bands represent the resistance value, while one band acts as a multiplier.
- In the 4 color band, two bands show the resistance value, one band is the multiplier, one band shows the tolerance value.
- In 5 colored bands, three bands show the resistance value, one band is the multiplier, one band shows the tolerance value.
- In 6 colored bands, three bands show the resistance value, one band is the multiplier, one band shows the tolerance value, one band shows the temperature coefficient.
How are resistor color codes calculated?
- Step 1: Open the resistor color code calculator from the link here.
- Step 2: Please choose the color of the tires in order.
- Step 3: Select the ohm display value.
- Step 4: Select the margin of error of the value.
- Step #5: If there are more than four bands on the resistance, access the resistance color code calculator here.
- Step #6: Choose the number of tires.
- Step #7: Please choose the color of the tires in order.
- Step #8: Select the ohm display value.
- Step #9: Select the margin of error of the value.
- Step #10: The operation is complete.

You can use the tools in the steps to calculate the resistor color code. Because the ohm value can increase with the strength of the resistor Choosing the impression value is extremely important. Since the resistance value in electrical systems can change for many different reasons, it is equally important to consider the margin of error.
Resistance color codes and values:

As you can see from the table above, it is possible to know the resistor values ​​that resistor color codes generally correspond to without using a math tool. LIKE I CAN’T LEAVE ON THE STREET You can take into account the colors Black, Brown, Red, Orange, Yellow, Green, Blue Purple, Gray, White respectively with the increasing value in the abbreviation.
Indicates the value of the resistance that regulates the current in the electrical system What are color codes of resistors, how to calculate? We’ve answered the curious questions and introduced some tools to help you calculate resistance color values. Once you master the subject, you can easily remember such codes and associated values.
