Resistivity is normally symbolized by the greek letter rho . Units are either ohm-meter (SI) or circular-mil ohms per foot (US). It describes the specific resistance of a sample of material that has particular length and cross-sectional area.
Another AnswerIn SI, resistivity is measured in ohm metres.
In North America, it is measured in ohm circular-mil per foot.

The unit of resistivity is ohm-meter (Ω·m) in the International System of Units (SI). Resistivity is a measure of a material's resistance to the flow of electric current. It is used to characterize the electrical properties of a material.
The SI unit of measurement for resistivity is the ohm metre, although it is often expressed in terms of microhm metres.
Conductivity is the reciprocal of resistivity, and its SI unit of measurement is the siemens per metre.
The SI unit for resistivity is the ohm metre.
In North America, resistivity is measured in ohm circular-mils per foot (which is often incorrectly written as 'ohms per circular-mil foot').
Conductivity is the reciprocal of resistivity, and is measured in siemens per metre (S/m). (Resistivity is measured in ohm metres)
The SI unit for conductance is the siemens (S). A siemens is the reciprocal of the ohm. A siemens also equals how many amperes divided by voltage.
The SI unit of conductance is the Siemens and is abbreviated as S.
It is also known as the mho, but that use is not SI.
The resistivity of the material can be calculated using the formula: resistivity = resistance x cross-sectional area / length. Plugging in the values: resistivity = 20 ohm x 2 cm / 10 cm = 4 ohm cm. Since resistivity is measured in ohm meters (SI unit), the resistivity of the material in SI unit would be 0.04 ohm meter.
Resistivity is a measure of a material's ability to resist the flow of electric current. It depends on factors such as the material's temperature, composition, and impurities. Materials with high resistivity impede the flow of electrons more than those with low resistivity.
The resistivity of a material does not depend on the diameter of the wire. Resistivity is an intrinsic property of the material and is constant regardless of the wire's diameter.
No, resistivity cannot be negative. Resistivity is a material property that indicates how strongly a material opposes the flow of electric current. It is always a positive quantity, even though some materials may have very low resistivity values.
The resistivity of deionized water is high, meaning it is a good insulator. It is higher than the resistivity of tap water or seawater, which have more dissolved ions and conduct electricity better.
