Resistivity - Wikipedia, the free encyclopedia

Electrical resistivity (also known as specific electrical resistance or volume resistivity ) is a measure of how strongly a material opposes the flow of electric current. A low resistivity indica...
en.wikipedia.org/wiki/Resistivity
Whether or not a material obeys Ohm's law, its resistance can be described in terms of its bulk resistivity. The resistivity, and thus the resistance, is temperature dependent. Over sizable ranges of temperature, this temperature dependence can be predicted from a temperature coefficient of resistance.

The sheet resistance is a measure of resistance of thin films that have a uniform thickness. It is commonly used to characterize materials made by semiconductor doping, metal deposition, resistive p...
en.wikipedia.org/wiki/Sheet_resistance
In the case of the wire, resistivity is defined as the resistance in the wire, multiplied by the cross-sectional area of the wire, divided by the length of the wire. The units associated with resistivity are thus ohm.m (ohm - meters).

Therefore if the length is doubled, the >resistance is doubled. Interestingly, the relationship of resistance to >diameter is not so simple and the frequency of the current affects the >resistance ... The proportionality constant relating >resistance to the length and area of a wire is the resistivity of the wire.
