What does the color mean on a

The color on a resistor indicates its resistance value. The colors are read from left to right, with the first two colors indicating the significant figures, the third color indicating the decimal multiplier, and the fourth color indicating the tolerance.

For example, a resistor with a brown (1), black (0), red (2), and gold (5%) color code would have a resistance value of 100 ohms, with a tolerance of 5%.

The following table lists the colors and their corresponding values:

| Color | Significant Figure | Decimal Multiplier | Tolerance |

|---|---|---|---|

| Black | 0 | x1 | None |

| Brown | 1 | x10 | ±1% |

| Red | 2 | x100 | ±2% |

| Orange | 3 | x1,000 | ±3% |

| Yellow | 4 | x10,000 | ±4% |

| Green | 5 | x100,000 | ±0.5% |

| Blue | 6 | x1,000,000 | ±0.25% |

| Violet | 7 | x10,000,000 | ±0.1% |

| Gray | 8 | x100,000,000 | ±0.05% |

| White | 9 | x1,000,000,000 | ±0.02% |

In addition to the standard color codes, some resistors may also have a fifth color, which indicates the temperature coefficient. The temperature coefficient is a measure of how much the resistance of the resistor changes with temperature.
