Is resistivity of a good conductor high or low?
It is Low
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 kind of material has a high resistivity and prevents the movement of electrons?
An insulator
Does a good conductor has a high resistance?
No, a good conductor has a low resistance.
Is newspaper a thermal conductor?
Yes, it is a material with a high thermal conductivity.
Is resistivity of a good conductor high or low?
It is Low
What is it called if a material conducts easily?
It is said to have a low resistance:A low thermal resistivity for heatA low electrical resistivity for electricityA low opacity or high transparicyfor light.
Why is copper wire the best known conductor?
The best electrical conductor known is silver, not copper. Electrical resistivity of silver: 1,59.10-8 ohm.m Electrical resistivity of copper: 1,68.10-8 ohm.m A good electrical conductor has a very low electrical resistivity and a high electrical conductivity (the same principles for the thermal conductivity).
What are the uses of a conductor in high ressitance?
they are used to reduce the resistivity,owing to the fact that the conductor introduces current into the resistance
Is lead conductor?
Lead has high resistivity of current. So , lead is not conduct current. But lead has low resistivity of heat and it conduct heat..

Is copper has low resistivity or low resistance?
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.
What kind of material has a high resistivity and prevents the movement of electrons?
An insulator
Does alumina become conductive at high temperatures?
Alumina is a good electrical insulator; at high temperatures the resistivity is smaller than the resistivity at room temperature.
How depletion region become narrow?
In fabrication process low resistivity (ohm/cm) of material results to expansion of depletion region lower than high resistivity
What would make a good electrical?
An electrical insulator is a material whose internal electric charges do not flow freely. Rubber, glass, paper, and Teflon, which have high resistivity, are very good electrical insulators.
