Observations:

1. If the resistor is a 3 band type, the tolerance can be assumed as 20%

2. If the resistor is a 3 or 4 band type the temperature coefficient is not indicated.

 

Example: A resistor have bands in the next sequence of colors: red, violet, orange and silver (the sequence to read the strips or bands is from the end to the center).

Band 1 and 2, forms the number 27.

Band 3 indicates that we must multiply this value by 1 000. The resistance becames of 27 000 ohms.

Band 4 indicates that the tolerance is 10%.
