There are three or four color rings on the resistor. The first color ring is close to the resistor end, and the rest are the second, third, and fourth color rings in sequence. || || The first color ring indicates the largest digit of the resistance value, the second color ring indicates the second digit, and the third color ring indicates how many zeros the resistance value should have. The fourth color ring indicates the error of the resistance value. The numbers or meanings represented by the color rings are shown in Table 1. ||Table 1 Numbers or meanings represented by the colors on the color rings||Color category Number on the first color ring Number on the second color ring Number to be multiplied by the third color ring Error on the fourth color ring||Brown 1 1 10 ||Red 2 2 100 ||Orange 3 ……
