Which conductor can carry higher current if they are of the same gauge?

Copper is an excellent conductor of electricity and has a high electrical conductivity rating, which allows it to carry a larger current compared to other materials when they are of the same gauge. Its low resistivity means that it can transmit electricity with minimal power loss due to heat generation.

In practical applications, this property makes copper a preferred choice for wiring in electrical systems, as it can handle the same current more efficiently than other materials. Despite aluminum being a commonly used conductor as well, it has a higher resistivity compared to copper, meaning it would need to be of a larger gauge to carry the same current level safely. Other options, like nichrome and nickel, are not typically used for general conductive purposes in high-current applications because they have higher resistivities and are chosen more for their resistance properties in applications like heating elements rather than for carrying electricity.
