He pointed out, for instance, that at the temperature that Korean scientists claim LK-99 turns into a superconductor, the electrical resistance drops, but not to zero.

Resistance to Ground Resistance to ground is a measurement that indicates the capability of an item to conduct an electrical charge (current flow) to an attached ground connection.

“For example, one of the papers shows electrical resistance versus temperature, and when it comes to superconductivity there’s a very sharp drop in the resistance … the drop is much too sharp.

This article was originally published with the title “Electrical Resistance of the Human Body” in SA Supplements Vol. 34 No. 872supp (September 1892), p. 13937 doi:10.1038 ...

Electrical resistance is the next major thing multimeters can measure. Resistance is quantified in ohms, which are indicated by this horseshoe-like symbol, Ω, the Greek letter omega.

The conversion from electrical to hot water space heating and DHW can be expected to reduce the energy cost for heating by more than 20% in most cases.

Why worry about efficiency in electrical distribution, when superconductors have no resistance at all?
