However, you're likely thinking of superconductors. These materials have zero electrical resistance at very low temperatures. This means electricity can flow through them with no energy loss.
Here's a breakdown:
* Conductors: These materials have low electrical resistance, allowing electricity to flow easily. Examples include copper, silver, gold, and aluminum.
* Insulators: These materials have high electrical resistance, preventing electricity from flowing easily. Examples include rubber, glass, and plastic.
* Semiconductors: These materials have conductivity between conductors and insulators, and their resistance can be changed by various factors. Examples include silicon and germanium.
* Superconductors: These materials have zero electrical resistance below a critical temperature. This is a special state of matter, and examples include certain metals and ceramics.
So, while no material truly has *zero* resistance, superconductors come closest.
