What is a color ring resistor and how to correctly identify it? 2

2. Number of color rings for identifying resistors:

Common color ring resistors are divided into four rings, five rings, and six rings, with different numbers of rings representing different information:diode

4-ring resistor: The first two rings represent the first two digits of the resistance value, the third ring is the multiplier, and the fourth ring is the tolerance.

5-ring resistor: The first three rings represent the first three digits of the resistance value, the fourth ring is the multiplier, and the fifth ring is the tolerance.diode

6-ring resistor: The first three rings are the same as the 5-ring resistor, the fourth ring is the multiplier, the fifth ring is the tolerance, and the sixth ring represents the temperature coefficient.

3. Read the resistance value and multiplier:diode

The first two or three color rings (depending on the number of rings in the resistor) correspond to a number, and when these numbers are connected together, they form the basic numerical part of the resistance value. The next color ring (multiplier) tells us how many powers of 10 we need to multiply this number by.diode

4. Read tolerance:

The tolerance color ring indicates the possible deviation range of the nominal resistance value of the resistor. For example, gold represents ± 5%, silver represents ± 10%, and without a color ring, it represents ± 20%.diode
