Not as many free moving electrons
wiring is made of copper because, it is a superconductor and super heat resistant. It also loss negligable amount of enegy.
133 Kelvin, about -140 Celsius. This is the critical temperature of a mercury -based superconductor. It contains copper-oxide, a common theme, I believe, in high temperature superconductors
Copper has a conductivity of 57 MS/m, whereas Silver has a conductivity of 66.5 MS/m. Bosch Automotive Engineer's Handbook 2nd Ed. 1987 Delta Press ISBN:1-85-226-00-9
No. Salt water is a conductor but not a superconductor.
American Superconductor was created in 1987.
An ideal superconductor has exactly zero losses, thus resistance is zero.
No, water is not a superconductor. Superconductors are materials that can conduct electricity with no resistance at very low temperatures. Water does not have the properties necessary to exhibit superconductivity.
A superconductor floating works by using the Meissner effect, which causes the superconductor to repel magnetic fields. This creates a magnetic field that locks the superconductor in place above a magnet, allowing it to float without any friction or resistance.
