Resistor Color Codes Calculator 
Calculate the resistance and tolerance for:
Red - Red - Red - None
Resistance color code values:
| Color | Band 1 | Band 2 | Band 3 (Multiplier) | Tolerance |
|---|---|---|---|---|
| Black | 1 | 1 | 1 | N/A |
| Brown | 1 | 1 | 10 | N/A |
| Red | 2 | 2 | 100 | N/A |
| Orange | 3 | 3 | 1000 | N/A |
| Yellow | 4 | 4 | 10000 | N/A |
| Green | 5 | 5 | 100000 | N/A |
| Blue | 6 | 6 | 1000000 | N/A |
| Violet | 7 | 7 | 10000000 | N/A |
| Gray | 8 | 8 | N/A | N/A |
| White | 9 | 9 | N/A | N/A |
| Silver | N/A | N/A | 0.01 | 10% |
| Gold | N/A | N/A | 0.1 | 5% |
| None | N/A | N/A | N/A | 20% |
Band 1 Value:
Red = 2
Band 2 Value:
Red = 2
Band 3 Value:
Red = 100
Tolerance Value:
None = 20%
Calculate ohms:
Ohms = (Band1 & Band 2) x Band 3 Multiplier
Ohms = 22 x 100
Ohms = 2200
