The Resistance color codes are used to indicate electronic ratings, with four, five, or six stripes of colors predominantly formed above the resistance. According to the value of these colors, the value of resistance comes out. Usually for resistors, but also for capacitors, inductors, diodes, and others. A separate code, a more then 20-pair color code, is used to identify wires in some telecommunications cables. Various codes are used for wire leads on devices such as transformers or building wiring. Internationally, a color code system is used to find the values of resistance. let's know more about Electronic Color Code In Electronics Engineering.
