Resistor Calculator is an App to help the user find the value of a resistor.
The fourth band is the tolerance (Gold or Silver) if there is no band the tolerance is 20%. The first three bands are colored: Black = 0 Brown = 1 Red = 2 Orange = 3 Yellow = 4 Green = 5 Blue = 6 Violet = 7 Gray = 8 White = 9 The fourth band (if any) is colored: Gold = 5%, Silver = 10%, (NONE = 20%)

Examining resistor 5, the first 3 bands are brown, black and blue and the fourth band (the multiplier) is green. So, these colors convert into 1 0 6 × 100,000 which calculates to 10,600,000 ohms or 10.6 Meg ohms. The brown 5th band and the red 6th band mean that the resistor has a 1% tolerance and a 50 ppm temperature coefficient.
The Resistor Color Code Calculator decodes and identifies a value and tolerance of 4 band wire wound resistors. More online conversion calculators at Digi-Key.
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.
Standard Resistor Values and Color
brown red orange yellow green blue violet gray white: black brown red orange yellow green blue violet gray white gold silver: black brown red orange yellow green blue violet gray The 4 color band resistor color code green-blue-black-gold stands for 56 Ω +/-5%, in words: fifty-six Ohms with plus/minus five percent tolerance.
Green and blue are the first significant digits (56); brown is the multiplier (10 1 = 10) and gold is the tolerance (5%). 56 x 10 = 560Ω. If the 3rd band would be red instead of brown, the multiplier would be (10 2 = 100) instead of 10 and the resistor value would be 56 x 100 = 5600 ohms = 5.6 k ohms.
brown – 1 . red – 2 . orange – 3 . yellow – 4 . green – 5 . blue – 6 . violet – 7 . grey – 8 . white – 9. The 3rd band or multiplier band is color coded as follows: If the nominal value was 34 Ohm and the 4th band of the resistor was gold (5%) the value range would be nominal +/- …
Dec 13, 2005 · Brown – Green – Black – Red – Brown that read 15K on my ohmmeter. The fourth band confuses me – it is definitely red not orange – any ideas why? Oh, and there is a red spot that joins the red and the brown. Similarly I have some 8.25K resistors that are: Grey – Red – Green – Brown – Brown with a red dot joining the two browns.
Five-band resistor color codes (PDF file for 5-band color codes) Example: (five bands) Yellow, White, Yellow, Brown, Gold Yellow, white and yellow represent 4, 9 and 4, respectively. Those consist of the first, second and third digits, so it will be 494. The forth band is brown.
