How to read the resistance value of the color ring resistor 2

To read the resistance value of the color ring resistor, the following steps need to be followed:

1. Determine the order of the colored bands: usually from left to right, they are the first digit, the second digit, the multiplication factor, and the tolerance value.diode

2. Identify the color of each colored ring: Each color represents a numerical value or multiplication factor. The color coding table of the color ring resistor can be used for accurate identification.

3. Calculate the resistance value of the resistor: Based on the values or multiplication factors represented by each ring, combine them according to certain rules to calculate the final resistance value.diode

4. Determine the tolerance range: Determine the allowable error range of the resistance value based on the color of the tolerance ring.diode

If there is a fifth ring, it represents the temperature coefficient, and the rate of change of resistance value with temperature can be determined based on color.

It should be noted that when reading the resistance of the color ring, one should carefully distinguish the order and color between the colored rings. Correctly identifying and calculating the value of each ring can accurately determine the resistance value of the color ring resistor.diode
