Which common factor affects both resistance and resistivity and how?

Answer

• The answer to the question is temperature which is the common factor between resistance and resistivity.
• EXPLANATION:
• Mathematically it can be written as.
• Hence, the common factor which is same for resistance and resistivity is temperature.

On what factors does the resistance and resistivity depend?

Resistance of a conductor depends on length of the conductor and area of cross section of the conductor, resistivity and temperature. Resistivity is a materialistic property depends on the material and temperature of the conductor.

What factors affect the resistance and how?

There are four factors affecting resistance which are Temperature, Length of wire, Area of the cross-section of the wire, and nature of the material. When there is current in a conductive material, the free electrons move through the material and occasionally collide with atoms.

What are the two factors affecting resistance?

There are several factors that affect the resistance of a conductor;

• material, eg copper, has lower resistance than steel.
• length – longer wires have greater resistance.
• thickness – smaller diameter wires have greater resistance.
• temperature – heating a wire increases its resistance.

Is resistivity a factor of resistance?

Resistivity and Conductivity The factor in the resistance which takes into account the nature of the material is the resistivity . Although it is temperature dependent, it can be used at a given temperature to calculate the resistance of a wire of given geometry.

What is the difference between resistance and resistivity?

Resistance is the physical property of a substance because of which it opposes the flow of current i.e. electrons. Resistivity is the physical property of a particular substance which is having particular dimensions.

What is meant by the resistivity of A material?

Resistivity of the material is defined as the resistance offered to current flow by a conductor of unit length having unit area of cross-section. It is the property of the material, does not depend on physical dimensions. Unit is ohm-metre(Ωm) Resistance of an object is related to resistivity as follows: R=Aρ l.

What is resistivity physics?

resistivity, electrical resistance of a conductor of unit cross-sectional area and unit length. Resistivity, commonly symbolized by the Greek letter rho, ρ, is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l; ρ = RA/l.

How are resistance and resistivity related?

Relation between Resistivity and Resistance is: R=ρlA, where ρ is the resistivity, l is the length of the conductor and A is the cross sectional area. Resistivity decreases with the decrease in temperature and increases with the increase in temperature.

What are two difference between resistance and resistivity?

Also, resistance is an aspect that opposes the flowing of free electrons. In contrast, resistivity is any material’s property that tells the resistance of the material with a particular dimension….Difference between Resistance and Resistivity.

Parameter	Resistance	Resistivity

What are the factors that affect the resistivity of materials?

Temperature. Alloying. Mechanical stressing. Age Hardening. Cold Working. The resistivity of materials changes with temperature. Resistivity of most of the metals increase with temperature. The change in the resistivity of material with change in temperature is given by formula given below-

What are the factors that affect the resistance of a conductor?

Length. Resistance of a uniform conductor is directly proportional to its length. When length increases, resistance increases. Cross-Sectional Area. The resistance of a uniform conductor is inversely proportional to its cross-sectional area. When cross-sectional area increases, resistance decreases.

How does temperature affect the resistivity of formation fluids?

The resistivity of formation fluids and water-based drilling muds varies greatly with temperature, but little with pressure. The temperature in a borehole can be

How does impurity affect the electrical resistivity of a solid?

Due to which the electrical resistivity of the solid solution increases more rapidly with increase of alloy content. A small content of impurity may increase the resistivity metal considerably. Even the impurity of low resistivity increases the resistivity of base metal considerably.
