As defined by Arduino to Go, every shade band on the resistor corresponds to a quantity however this could differ relying on the band’s placement. It’s not difficult, however the sheer variety of colours and the way their placement can have an effect on a resistor’s Ohm worth makes making an attempt to memorize every part considerably difficult. In essence (once more, relying on placement):

1. Brown is one, or a multiplier of 10.
2. Red is 2, or a multiplier of 100.
3. Orange is three, or a 1,000 multiplier.
4. Yellow is 4, or a multiplier of 10,000.
5. Green is 5, or a multiplier of 100,000.
6. Blue is six, or a 1,000,000 multiplier.
7. Purple is seven, however has no multiplier.
8. Grey is eight, additionally with no multiplier.
9. White is 9, no multiplier.
10. Black is a zero, or a multiplier of 1.

Silver and gold are the 2 exceptions to this sample in that they do not signify a quantity or multiplier. Instead, they point out a 10- to 5-percent (respectively) vary in accuracy — that means a gold band resistor may have a 5-percent greater or decrease Ohms worth attributable to attainable variance within the manufacturing course of.
