Which of the following materials typically has the lowest resistance?

Copper is known for its excellent electrical conductivity, which means it has very low resistance to the flow of electric current. This property makes it an ideal choice for electrical wiring and components because it allows electrical energy to pass through with minimal energy loss.

The structure of copper at the atomic level allows electrons to move freely, facilitating this efficient conduction of electricity. In contrast, materials like wood, rubber, and plastic are insulators that impede the flow of electrical current, resulting in higher resistance. These materials have fewer free electrons available for conducting electricity, making them less effective in transmitting electrical energy. Therefore, copper stands out as the material with the lowest resistance among the given options.
