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 Ï (rho). The SI unit of electrical resistivity is theohmâ‹…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.
What else can I help you with?
If the diameter of wire is double what is resestivity?
Resistivity won't change. Resistivity is a material property that doesn't depend on the shape.
What is resistivity on what factor is depends?
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.
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 change in resistivity if length is doubled?
Resistivity is a property of a substance, and doesn't depend on the dimensions of a sample. If the length of a conductor is doubled, then its resistance doubles but its resistivity doesn't change.
If the diameter of wire is double what is resestivity?
Resistivity won't change. Resistivity is a material property that doesn't depend on the shape.
Do resistivity depend upon area of crosss-section?
No. Resistance does.
Which common factor affects both resistance and resistivity and how?
Temperature is a common factor that affects both resistance and resistivity. As temperature increases, the resistivity of conductive materials typically increases due to increased atomic vibrations, which impede the flow of electrons. Consequently, this rise in resistivity leads to an increase in resistance for a given material. Thus, both resistance and resistivity are influenced by temperature, impacting the efficiency of electrical conduction.
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

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.
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 change in resistivity if length is doubled?
Resistivity is a property of a substance, and doesn't depend on the dimensions of a sample. If the length of a conductor is doubled, then its resistance doubles but its resistivity doesn't change.
Does resistivity depends upon dimension of the conductor?
Yes, resistivity does depend on the dimensions of the conductor. The resistivity of a material is an intrinsic property, but the resistance of a conductor is also influenced by its dimensions such as length, cross-sectional area, and shape. These dimensions affect the resistance of the conductor through the formula R = ρ * (L/A) where ρ is resistivity, L is length, and A is the cross-sectional area.
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.
What are four factor that determine resistance?
There are three, not four, factors that determine the resistance of a conductor. These are the length of a conductor, its cross-sectional area, and its resistivity.As resistivity is affected by temperature, you could say that temperature indirectly affects resistance but, strictly, temperature is affecting the resistivity not the resistance -which is why it is not considered a 'fourth' factor.So, resistance = resistivity x (length/area)
