Standard metal wires get worse at conducting electricity as they get thinner, ultimately limiting the size, efficiency, and performance of nanoscale electronics. In a paper published Jan. 3 in Science ...

Other materials can also conduct electricity, as long as they let the charge flow freely through them. Like the graphite in a pencil. Or this salty water. Now, the outside of electric wires are ...

He asserts that as the inside or conducting copper wire? of it are small and laid parallel, while the outside protecting iron wires are twisted and laid on the top of a soft material, that when ...

Wires have metal inside to carry electricity. Copper and aluminum are often used because they’re good at conducting electricity. Tap to read more.
