What is resistivity and what factor does it depend?
Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows the movement of electric charge. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is theohm⋅metre (Ω⋅m)It defined as resistance offerde by a unit length and cross section area conductor.It depends on material used.it depends on relexation time and temperature.
Is resistivity depends upon dimension of conductor?
Yes, resistivity is dependent on the material of the conductor, not its dimensions. Resistivity is an intrinsic property of a material that influences its ability to resist the flow of electrical current.
Is resistivity of a material depends upon the dimensions of a material?
Resistivity is an intrinsic property of a material and is not affected by the dimensions of the material. Resistivity is determined by the material's composition and structure. The resistivity of a material remains constant as long as the material is uniform.
Does resistivity depend on length and area of the cross section of the material?
No. Resistivity is a material constant, defined for a standard size of material. For another size of material, it can be calculated. Resistivity is the same for any piece of material; resistance can change.
What is the factor affecting the resistivity?
The factors affecting resistivity include the material's composition, temperature, and impurities present. Different materials have different resistivities due to variations in electron mobility and collisions with lattice vibrations. Temperature affects resistivity because it changes the lattice vibrations and electron collisions within the material. Impurities can also increase resistivity by disrupting the flow of electrons.

Why does the electrical resistivity of a conductor does not depend on its dimensions?
resistivity and resistance are two diff. things...........resistance depends on length and thickness resisitivity too depends on the area and length resistivity=resistance*area/length

Yes, resistivity is dependent on the material of the conductor, not its dimensions. Resistivity is an intrinsic property of a material that influences its ability to resist the flow of electrical current.
The resistance of a wire depends on the?
The length, cross-sectional area, and resistivity. As resistivity changes with temperature, temperature indirectly affects resistance.
Which common factor affect both resistance as well as resistivity and how?
Temperature is a common factor that affects both resistance and resistivity. An increase in temperature generally leads to an increase in resistance and resistivity of a material. This is because higher temperature causes more atomic vibrations and collisions within the material, hindering the flow of electrons and increasing resistance.
Is resistivity of a material depends upon the dimensions of a material?
Resistivity is an intrinsic property of a material and is not affected by the dimensions of the material. Resistivity is determined by the material's composition and structure. The resistivity of a material remains constant as long as the material is uniform.
Water resistivity depends on?
Several factors influence water resistivity. Some of the most important are 1) the concentration of ions in the water; 2) the mobility of the ions in the water (smaller ionic radius ions tend to decrease water resistivity more than larger ionic radius ions); 3) the oxidation state of the ions; and 4) the temperature of the water.
Does resistivity depend on length and area of the cross section of the material?
No. Resistivity is a material constant, defined for a standard size of material. For another size of material, it can be calculated. Resistivity is the same for any piece of material; resistance can change.
How would you calculate current carrying capacity of the ACSR or AAAC conductor?
* ACSR or AAAC or anything else, it does not matter. * Conductivity depends on resistance of material and resistance depends on resistivity of material and some other factors. * Resistivity of any material is generally constant term and depends on material. resistivity of alluminium and cooper is different. * General equation for calculation of resistance is: R= SL/A where, R=resistance of material S=resistivity of material L = length of material and A = area of material and now finally I = V/R where, I = max. current which can pass at given voltage and temperature V=voltage applied R=resistance of material as calculated above remember R also depends on temperature also and varies with temperature....so for large change in temp. you will have to also consider that factor.

How does resistivity depends on temperature of conductors?
The resistance of a simple conductor normally rises as its temperature rises.
How would you describe the magnetic field produced by a current in a straight wire?
Yes. It depends on its resistivity
