![]() However they too can depend on multimeter to identify resistance values. The next drawback is for a specific group of people color blind people can not identify the device using color codes. But this is not a major concern as the exact value can be easily identified using a multimeter (in case of confusion). The first one appeals to general users where it becomes difficult to distinguish between colors (for example Red and Brown ) when the component is over heated. This technique of color coding has 2 disadvantages. Color coding technique makes it easy to print values (based on color codes) on small components, such as resistors and facilitates cost effective manufacturing. Hence a standard was formed in 1920 by then Radio Manufacturers Association (now part of EIA Electronic Industries Alliance) to identify values and ratings of electronic components by printing color codes on them. Electronic components like resistors are very small in size and its difficult to print its value directly on to the component surface. ![]() In the case of resistors, color coding is used to identify a specific resistance value, for example a 100 ohms resistor or a 1 kilo ohms resistor with 5% tolerance. 1 RESISTANCE COLOR CODING Resistor Color Code Chart Understanding Color coding is used in electronics to identify between different components.
