Carbon resistors are most common in electronic equipment. They consist of a high-grade ceramic rod or cone ( called the substrate on which is deposited a thin resistive film of carbon.
The numerical value of their resistance is indicated by a color code which consists of bands of different colors printed on the body of the resistor. The color used in this code and the digits represented by them are given in the table below:
Usually, the code consists of four bands. Starting from left to right.
The 5 band resistor color bands are interpreted as follows:
Certain precision resistors with a tolerance of 2 %, 1 %, or less are generally color-coded with five bands as shown in the figure given below:
