Example: 4 rings Resistance in order: red yellow red gold read 2700Ω=2.7K error ±5%

Example: 4 rings Resistance in order: orange, white, red, silver read 3900Ω=3.9K error ±10%

Example: 4 rings of Resistance in order: orange orange gold and silver where orange orange is 33 multiplied by 10-1=3.9Ω error is ±10%

Example: The Resistance of 4 rings is in order: yellow purple silver silver where yellow purple is 47 multiplied by 10-2=0.47Ω error is ±10%

From the above, read the third color ring for gold or silver must pay attention to, because it is multiplied by negative number, Resistance value is generally 0.1-9.9Ω.
