Grounding systems without low resistivity to the ground can still be effective in protecting a structure from lightning damage.
An even better material than copper, except for its high cost, would be silver as this has even lower resistivity.
Also the higher the n-value then the "better" the superconductor as the lower the resistivity at a certain current.
ReO is unusual for an oxide because it exhibits very low resistivity.
Archaeological features can be mapped when they are of higher or lower resistivity than their surroundings.
Silver has a slightly lower resistivity than copper, which allows a thinner wire to have the same resistance.
Copper, with lower resistivity than aluminium, was the conductor of choice for most power systems.
A low resistivity indicates a material that readily allows the movement of electric charge.
A conductor such as a metal has high conductivity and a low resistivity.
Most metals have a very low electrical resistivity.
