The length of a conductor influences its resistance, not its resistivity. Resistivity is an intrinsic property of the material itself, defined as the material's ability to resist electric current, and is independent of the conductor's dimensions. However, as the length of a conductor increases, its resistance increases proportionally, following the formula ( R = \rho \frac{L}{A} ), where ( R ) is resistance, ( \rho ) is resistivity, ( L ) is length, and ( A ) is cross-sectional area. Thus, longer conductors have higher resistance due to the greater distance that electrons must travel.
What else can I help you with?
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
What are the factors affecting the resistance of conductors?
Conductor resistance = Conductor resistivity * Length of conductor / Cross sectional area of conductor. So. It is directly proportional to material & conductor length. And inversely proportional to the cross sectional area of conductor.
What happens to resistance when length of conductor is doubled without affecting thickness of conductor?
Nothing. Resistivity is a physical characteristic of a material. It's not affected by its shape, etc.
If A conductor has a resistance of 0.8 ohms what will happen to its resistance if the temperature is decreased?
The resistance of a conductor is directly proportional to the resistivity of the conductor. since the resistivity of a conductor is decreases with decrease in temperature hence the resistance.
What is the value of resistivity?
Electrical resistance is measure in Ohms. A function of voltage divided by current. It is also dependant on the length and cross sectional area of the conductor.
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.
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 resistivity of material?
the electrical resistance of a conductor through unit cross-sectional area per length is called "resistivity of material"
When the length is increased 2 times the value for resistivity will be?
The value for resistivity will remain unchanged (provided temperature remains constant). Resistivity is a property of the material. The resistance, however, will double. Remember that resistance is directly proportianal to the length of the conductor and inversely proportional to the cross-sectional area of the conductor.
What are the factors affecting the resistance of conductors?
Conductor resistance = Conductor resistivity * Length of conductor / Cross sectional area of conductor. So. It is directly proportional to material & conductor length. And inversely proportional to the cross sectional area of conductor.
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.
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)
Resistance of a copper conductor will decrease with an increase of applied voltage?
Resistance is affected by the length, cross-sectional area, and resistivity of the conductor. The resistivity, in turn, is affected by temperature. So only by changing one of these four factors will the resistance of a conductor change. Changing voltage will have no affect upon the conductor's resistance.
What happens to resistance when length of conductor is doubled without affecting thickness of conductor?
Nothing. Resistivity is a physical characteristic of a material. It's not affected by its shape, etc.
What are the four factor affect resistace in a conductor?
The four factors that affect resistance in a conductor are the material's resistivity, the length of the conductor, the cross-sectional area, and the temperature. Resistivity is an intrinsic property of the material, where some materials, like copper, have lower resistivity than others. Resistance increases with the length of the conductor and decreases with a larger cross-sectional area. Additionally, as temperature rises, resistance typically increases for most conductors due to increased atomic vibrations that impede electron flow.
What is the resistance formula?
R= ρL/A ρ- electrical resistivity of the materialL- length of the conductor.A- cross sectional area of the conductor.
