The Color Code

The color code is a standardized system used on electronic components, such as resistors and capacitors, to indicate their values and tolerances through colored bands or markings. For resistors, each color corresponds to a specific number, allowing quick identification of resistance value and accuracy without needing to read small numbers. Commonly, the order of the color bands helps determine the significant figures, multiplier, and tolerance. This system enables technicians and engineers to efficiently select and verify component specifications during manufacturing, repair, or testing processes, ensuring proper functioning of electronic circuits.
