Define the term resistivity
WebResistivity, commonly symbolized by the Greek letter rho, ρ, is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l; ρ = RA /l. The unit of resistance is the ohm. In the metre-kilogram … WebWe can define the resistivity in terms of the electrical field and the current density, (5.3.1) The greater the resistivity, the larger the field needed to produce a given current density. The lower the resistivity, the larger the current density produced by a given electrical field. Good conductors have a high conductivity and low resistivity.

WebSep 12, 2024 · The unit of resistivity in SI units is the ohm-meter \((\Omega \cdot m\). We can define the resistivity in terms of the electrical field and the current density. \[\rho = … Electrical resistivity (also called specific electrical resistance or volume resistivity) is a fundamental property of a material that measures how strongly it resists electric current, such as pure water which is an insulator. A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is the ohm-meter (Ω⋅m). For example, if a 1 m solid cube of material has sheet contact…
