Electrical circuits should not use what material as conductors?

The reason gas piping or components should not be used as conductors in electrical circuits is primarily due to safety and material properties. Gas piping is designed exclusively for transporting gas and is not manufactured to handle electrical currents. Using it in electrical applications can lead to serious hazards, including the risk of electric shock, fire, or explosion.

Gas piping is typically made from materials that are not conducive to effective electrical transmission. Furthermore, if gas piping is energized with electricity, it could pose risks like corrosion or degradation of the piping material, compromising its integrity and safety for transporting gas.

In contrast, materials such as copper wires and aluminum foil are specifically designed and rated for electrical applications, making them appropriate conductors. Choices like iron bars can have uses in certain electrical contexts, but they also come with limitations in conductivity compared to other materials.

Thus, the inherent design and intended use of gas piping firmly establish why it should never be used as a conductor in electrical circuits.
