The color band system is a method used to indicate the values of resistors through a series of colored bands printed on their bodies. Each color corresponds to a specific number, and the sequence of colors determines the resistance value and tolerance. Understanding the color code is essential for anyone working with electronic components to ensure proper circuit functionality. **Key Points:** - Color bands indicate resistance values and tolerance. - Each color represents a specific number or multiplier. - The first two bands denote significant digits, the third band indicates the multiplier, and the fourth denotes tolerance. | Color | Number | Multiplier | Tolerance | | ------ | ------ | ---------- | --------- | | Brown | 1 | x10 | ±1% | | Red | 2 | x100 | ±2% | | Orange | 3 | x1,000 | | | Yellow | 4 | x10,000 | | | Green | 5 | x100,000 | ±0.5% | | Blue | 6 | x1,000,000 | ±0.25% | | Violet | 7 | | ±0.1% | | Gray | 8 | | ±0.05% | | Black | 0 | | | | Gold | | x0.1 | ±5% | | Silver | | x0.01 | ±10% |
