These cables can have totally different configurations based on their design on national and international regulations. 5. National Museum of American History, Washington, D.C.

There goal of electrical cables is to transport the electrical vitality from one point to a different destination. Different colours of wires have totally different shade for different purpose. Different types of cables are used at completely different requirement like Coaxial cables, twisted cable pair cables, etc. The color codes on the electrical cables help to establish their goal of usage and helps in correct operation and set up. These are essential for various application like energy technology, distribution and transmission. Coax are used for transmitting very high frequency alerts with very less lack of vitality like for appliances like radio, antennas, transmitters.
