resistivity
This term describes an intrinsic property of a material rather than a specific object. While resistance refers to the total opposition to current in a specific component, resistivity is a constant value for the material itself, regardless of its shape or size. It carries a technical, scientific connotation used primarily in physics, electrical engineering, and geophysics.
In geological contexts, the term shifts from electrical current to fluid dynamics. It describes the inherent difficulty fluids face when moving through porous structures like sandstone or shale. Because it is a measurement of a property, it is treated as an uncountable mass noun in most scientific discourse, referring to the general concept or the specific value of a substance.
