In the world of electronics Resistor plays a great roll. To know the value of a register there are Resistor Color Code chart. This color code is divided into 4 segments of a Resistor. From below image red color is brand A, violent is brand B, green is brand C & golden yellow is brand D. Brand C is also know as multiplier. Brand D is technically called Tolerance.
For example, a Resistor with bands of brown, orange, red, and gold will have first digit 1, second digit 3, followed by 2 zeros: 1,300 ohms. Gold signifies that the tolerance is ±5%.
| Color | Value | Multiplier | Tolerance |
| Black | 0 | x100 | – |
| Brown | 1 | x101 | ±1% |
| Red | 2 | x102 | ±2% |
| Orange | 3 | x103 | – |
| Yellow | 4 | x104 | (±5%) |
| Green | 5 | x105 | ±0.5% |
| Blue | 6 | x106 | ±0.25% |
| Violet | 7 | x107 | ±0.1% |
| Gray | 8 | x108 | ±0.05% (±10%) |
| White | 9 | x109 | – |
| Gold | – | x10-1 | ±5% |
| Silver | – | x10-2 | ±10% |
