1. Determine the order of the colored bands: Typically, from left to right, they represent the first digit, the second digit, the multiplier, and the tolerance value.diode

2. Identify the color of each colored band: Each color represents a numerical value or a multiplier. The color code table of a color-coded resistor can be used for accurate identification.

3. Calculate the resistance value: Based on the numerical values or multiplication factors represented by each color band, follow a specific rule to combine and compute the final resistance value.diode

4. Determine the tolerance range: Based on the color of the tolerance band, identify the permissible error range for the resistor value.

5. If there is a fifth band, it represents the temperature coefficient, which can be used to determine the rate of change in resistance value with temperature based on its color.diode

It should be noted that when reading a color-coded resistor, care must be taken to distinguish the order and colors of the colored bands. Correct identification and calculation of each band's value can accurately determine the resistance of the color-coded resistor.diode
