Nothing. Resistivity is defined as specific resistance. However, Resistivity is different from resistance.

Answer:

Resistance is the opposition offered by the material which is of any shape and size whereas resistivity is the resistance offered by the material with unit area of cross section and unit length.

Therefore, resistance varies depending upon shape and size of the material while resistivity is constant for a particular material.

What is the difference between resistance and the resistivity?

Resistance is the value of a given wire in ohm but resistivity is value of the material with which that wire is made in ohm meter. R = rho * L / A Here rho is resistivity and R is resistance. L is the length of the wire and A is area of cross section


What is the Difference between reluctance and resistivity?

Resistivity is the intrinsic property of a conductor, and it is independent of the size of that conductor. Resistance is an extrinsic property that makes it dependent upon the amount of the material that there is present.


What is the relationship between resistivity and circumference?

The relationship between resistivity and circumference is inverse.The resistance of a substance decreases as the surface area of that substance increases. The greater circumference presents a greater conduction surface.AnswerThe original answer describes resistance, NOT resistivity. Additionally, it is incorrect because resistance is inversely-proportional to cross-sectional area NOT circumference!There is NO relationship between resistivity and the circumference of a material. Resisitivity is a constant at any given temperature and is completely unaffected by the dimensions of a material.


What is the difference between metal and semiconductor?

A semiconductor's resistivity decreases with increasing temperature. A metal's resistivity increases with increasing temperature.


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 happens to the resistance as the area increases?

Double the area means half the resistance. Resistance = resistivity times length / area. Resistivity is a property of the material only.


How do you calculate a cross-sectional area When all you know is resistance resistivity and length?

I think the equation you are looking for is Resistance (ohms) = Resistivity * Length / Area or R=p*L/A. This is the resistance of a circular wire with cross-section of A, length of L, and material with resistivity p. So to get area: Area = Resistivity * Length / Resistance.


The resistance of a wire depends on the?

The length, cross-sectional area, and resistivity. As resistivity changes with temperature, temperature indirectly affects resistance.


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.


Is electrical resistance and electrical resistivity the same?

No, they are not the same. Electrical resistance is a measure of how much a material opposes the flow of electric current, while resistivity is a property of the material itself that determines its resistance. Resistivity is an intrinsic property of the material, while resistance depends on the dimensions and shape of the material.


What is the formula for resistivity?

Resistance (Ohms) = Voltage (v) / Current (I)


What is a resistance of a material?

Resistance is the opposition to the flow of electric current. It is affected by the length, cross-sectional area, and resistivity of a material. As resistivity is affected by temperature, temperature indirectly affects resistance.
