How do I determine the colour code of a resistor?
Reading and Determining the Resistor Value Hold the resistor with the gold or silver band to the right and read the color codes from the left to the right. Select the color codes from the bands on the resistor. Read the colors from left to right. The resistance value based on the color code provided is now displayed.
What is colour code of resistor?
Resistor Colour Chart
| Colour | 1st Band | Tolerance |
|---|---|---|
| Yellow | 4 | |
| Green | 5 | ± 0.5% (D) |
| Blue | 6 | ± 0.25% (C) |
| Violet | 7 | ± 0.10% (B) |
What is resistor color coding chart?
The four band color code is the most common variation. These resistors have two bands for the resistance value, one multiplier and one tolerance band. By using the color code chart, one finds that green stands for 5 and blue for 6. The third band is the multiplier, with red representing a multiplier value of 2 (102).
What are the color codes of resistors?
Black: 0
What do the colors on resistors indicate?
The resistor color code indicates the electronic value of a resistor. Manufacturers devised the universal electronic color code rating system in the early part of the twentieth century because the bands of color were much easier to read on a small resistor than tiny print, and were also cheaper to produce.
What is the history of the resistor color code?
The resistor colour code was invented in the 1920s by the Radio Manufacturers Association (RMA). All leaded resistors with a power rating up to one watt are marked with colour bands. They are given by several bands and together they specify the resistance value, the tolerance rate and sometimes the reliability or failure rates.
What is the color code for 10 ohm resistor?
For a 10 ohm carbon resistor, the color code would be Brown, Black and Black with Brown and Black indicating the value 10 and the third black indicating that 10 has to be multiplied by 10 raised to power of 0.
