The total resistance is therefore: 1kΩ ± 5% Ω. This example uses a gold band, giving us a tolerance of 5%. The most common values are 5% for gold, and 10% for silver.

So the total value of the resistance given by the colors is 10 x 10 2 Ω = 1000 Ω = 1kΩ.īand Four – Tolerance: Gives the value of the tolerance for the resistor. In this case, the third band is red which corresponds to the number 2. The actual multiplier is 10 n, where n is the value of the band color. Therefore the digits from band one and band two are: 10.īand Three – Multiplier: Takes the digits and multiplies them by a value given by this band. This is added to the right of the first digit (from band one). This band is black, which corresponds to the value 0. The first band is brown, which corresponds to the value 1.īand Two – 2nd Digit: The second digit of the resistance value. Resistor color codes always have digits, followed by a multiplier, follower by a tolerance value.įor a four band resistor, each band has a specific role:īand One – 1st Digit: This is the first digit of the resistance value. 1K Resistor Color Chart Band Number Function Color Value 1 1st Digit Brown 1 2 2nd Digit Black 0 3 Multiplier Red x 100 4 Tolerance Gold (or silver) ± 5% Total Value:ġ000 ± 5% Ω How To Read the 1K Resistor Color Code This band is almost always gold or silver, so it is usually easy to identify.Ģ) Look for the gap between the 3rd and 4th band.
