The meaning of each color circle is as follows:

The first color ring: the first number of resistance;

The second color ring: the second digit of the resistor;

The third color circle: 10 power;

The fourth color circle: false representation.

For example: resistance color ring: brown, green, red, gold, first place:1; Second place: 5; Third place: the power of 10 is 2 (that is,100); The error is 5%; That is, the resistance value is:15×100 =1500ω =1.5ω =1.5k.
