What type of metal is particularly good for electrical applications due to its low resistance?

Copper is particularly good for electrical applications due to its low electrical resistance, which allows it to efficiently conduct electricity. This characteristic makes copper an ideal choice for wiring and electrical components where minimal energy loss is essential. The atomic structure of copper facilitates the free movement of electrons, resulting in high conductivity, meaning that electrical current can flow through it easily. This property is crucial in applications where performance and efficiency are key, such as in power transmission and electronic devices.

Aluminum is also a good conductor but not as effective as copper. Steel and iron, on the other hand, have higher resistance and are not commonly used for electrical wiring, making them less suitable for applications where low resistance is critical.
