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 composition, temperature, and dimensions. Materials with high resistivity impede the flow of current more than those with low resistivity.

What is resistivity and what factor does it depend?
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.
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?
Yes, resistivity depends on the length and cross-sectional area of the material. Resistivity is calculated using the formula ρ = R(A/L), where ρ is the resistivity, R is the resistance, A is the cross-sectional area, and L is the length of the material.
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

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?
Water resistivity depends on the concentration of ions and impurities present in the water. Pure water has a high resistivity, while water with high levels of dissolved salts and minerals has low resistivity. Temperature also plays a role, as resistivity tends to decrease with increasing temperature.
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.
Does resistivity depend on length and area of the cross section of the material?
Yes, resistivity depends on the length and cross-sectional area of the material. Resistivity is calculated using the formula ρ = R(A/L), where ρ is the resistivity, R is the resistance, A is the cross-sectional area, and L is the length of the material.

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
