Color coding circuits

Components and wires are coded are with colors to identify their value and function. Wiring for AC and DC power distribution branch circuits are color coded for identification of individual wires. In some jurisdictions all wire colors are specified in legal documents.

In that case, local custom dictates the “optional” wire colors. Are you having trouble reading resistor color codes?

If your answer is yes, then this tool is specifically designed for you!

Resistors are the most commonly used components in electronic circuits and devices.

The electronic color code is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others. A separate code, the 25-pair color code , is used to identify wires in some telecommunications cables.

Color Coding Wiring Schematics for Diagnostics. Wiring schematics are generally drawn in the “off” position. To help you simplify complex schematics, we can highlight circuits using the coloring scheme below to help us understand the flow of current through the circuit and components in both the “key off” position and the . Therefore, it is necessary to be familiar with this system. Used to identify conductors for point-to-point wiring and for circuit diagrams.

The colors are read from left to right. Most control cable color codes are adaptations of this method. Later, for ease and convenience, ink . But in order to do this the actual resistor needs to have some form of . The ability to restrict the flow of electric current is called resistance.

The resistors with high resistance value will restricts large amount of electric current whereas the . How does the resistor color code work? In the sections below examples are given for different numbers of bands, but first some tips are given to read the color code. Resistivity depends upon conductor to conductor. Some have less resistivity which is good conductor, some have high resistivity which is bad conductor.

It eliminates the use of cheat sheets or mental calculations or any other method you use now to determine the appropriate color of the circuit.
