WebResistivity is a measure of the material's ability to oppose electric current. This formula is not exact, as it assumes the current density is totally uniform in the conductor, which is not always true in practical situations. However, this formula still provides a good approximation for long thin conductors such as wires. new movies showing todayWeb29 dec. 2024 · If the resistivity readings in a specific area are lower or higher than their surroundings, archeologists can gain a better understanding of which features could be located below the ground. For instance, a stone structure could block the flow of electricity, which would result in lower resistivity readings than normal. new movies showing on netflixWebresistivity, electrical resistance of a conductor of unit cross-sectional area and unit length. A characteristic property of each material, resistivity is useful in comparing various materials on the basis of their ability to conduct electric currents.
