How to identify color ring resistors 3

(3) Remember the error represented by the fourth ring color, which is: gold is 5%, silver is 10%, colorless is 20%.

Here is an example to illustrate:diode

Example 1: When the four color rings are yellow, orange, red, and gold in sequence, the third ring is red and has a resistance range of several points and k Ω. By substituting the numbers "4" and "3" represented by the yellow and orange colors respectively, the reading is 43k Ω. The fourth ring is gold, indicating an error of 5%.diode

Example 2: When the four color rings are brown, black, orange, and gold in sequence, since the third ring is orange and the second ring is black, the resistance value should be several tens of k Ω. Substituting the number "1" represented by brown, the reading is 10k Ω. The fourth ring is gold, with an error of 5%.diode
