Copper is a material - although you can make objects from it.
Resistivity is a property of materials.
Resistance is a property of objects - it depends on the resistivity of the material the object is made of, the shape and size of the object, and also of where you connect to take your measurement.
With all this in mind:
Copper has a low resistivity.
Copper objects tend to have low resistance compared to other objects of similar shape and size made of materials with a higher resistivity
You can still achieve quite high resistances with a long enough piece of very thin copper wire.

∙ 13y agoCompared to other metals, zinc is a moderately good conductor. It is not as good as gold or platinum but not as bad as lead and tin. Compared to all elements, it is a good conductor. Compared to non-metals, metals like zinc, are much better conductors.

Why is copper wire not used in potentiometer?
Copper is not used in potentiometer due to the following reasons: 1)Low resistivity 2) High Temperature Coefficient of resistance
What are some examples of items with low conductivity?
Thermal resistance: diamond Electrical resistance: copper Optical resistance: quartz
Why copper is most commonly used semiconductive material?
Copper is a conducting material, not a semiconducting one. It's perhaps the most widely used conductor because it offers the best combination of low resistivity and low cost.
Five factors that affect resistance?
Electrical Resistance depends on three factors: Resistivity; Area; Length.Resistivity is the property of the matter. More Resistivity means more resistance.More Area means less resistance.More length means more resistance.R= Resistivity. Length/Area
Why are copper wires good?
Copper is good for use for electrical wiring because it has very low resistivity and is therefore an excellent conductor of electricity. It is not nearly as good a conductor as silver, but it is a lot less expensive.
Why copper strips are used in meter bridge wire?
The resistivity of copper is very low and as the strip is so thick then resistance would be almost zero.
Why is copper wire not used in potentiometer?
Copper is not used in potentiometer due to the following reasons: 1)Low resistivity 2) High Temperature Coefficient of resistance
Is resistivity the same for all materials with the same length?
Yes, because the resistivity does not depends on the length of any materials. Resistivity is constant.-Ariel DUmancas-No. The resistance in different materials is different. For example, Copper has a low resistance to electricity compared to plastic. This is also one reason why copper is used instead of plastic in wires. Knowing the resistance of different material helps decide what material should be use for different objects (like copper for wires in plastics)
Can copper and alluminium wire of same length and diameter have same resistance?
For a single temperature, yes. The copper wire will have a much smaller cross-section than the iron wire. For multiple temperatures, no. Copper and iron have different temperature coefficients for resistivity.
From copper and manganin which has higher resistance?
The question is actually wrong, they can both have the same resistance if configured differently, the real question should be which has a higher resistivity which is the electrical resistance found in a standard amount of each material. In this case Manganin has a higher resistivity than copper.
How do you convert conductivity to resistivity?
Conductivity is a measure of the ability of a substance to conduct electricity. Resistivity is a measure of how strongly a substance resists the flow of an electric current. So conductivity and resistivity are opposed to each other. A good conductor like copper has a low resistivity, and a good insulator like glass has a low conductivity and a high resistivity. Mathematically, conductivity and resistivity are inverses of each other, so it is quite easy to convert conductivity to resistance.
What is specific resistance and melting point of fuse?
low resistivity and low melting point.
What is specific-resistance?
Electrical resistivity is a measure of how a material opposes the flow of electric current. Copper is used for electrical lines because it has a low resistance relative to its cost. Gold and silver also have a low resistance, but imagine how expensive the power cord for your computer would be if it were made of gold!
What is the specific resistance of copper and aluminum?
Copper is widely use in the US, it has the second lowest resistivity, behind silver, which is much more expensive making copper the best choice. It resistivity at 20 °C is 1.72×10−8
Does a thin wire has more RESISTIVITy or a thin wire of the same material?
Resistivity is a property of the material only, not of the dimensions of the wire. The resistance of a wire is the resistivity times the length divided by the cross-section area. So a long wire has more resistance, a thicker wire has less resistance, even if they are both made of copper with the same resistivity.
Is copper low or high resistance?
Copper is low resiatance
How do you calculate resistivity of copper wire?
(rho) or resistivity of a "wire" is calculated using this formule:rho = Resistance x Area / length of materialthe resistivity of copper is 1.7 x 10 -8 ohm/mResistivity is measured in ohm metres, NOT ohms per metre!
