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
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.
No. Resistivity is a material property, and is defined as the resistance for a piece of material of some standard size.
Resistivity is a property of the material only, not of the dimensions of the wire. The resistance of a wire is the resistivity times the length divided by the cross-section area. So a long wire has more resistance, a thicker wire has less resistance, even if they are both made of copper with the same resistivity.
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.
Bulk resistance is the ohmic resistance of the semiconductor material. The natural resistance of a "P" type or "N" type semiconductor material.
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.
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.
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.
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
A semiconductor's resistivity decreases with increasing temperature. A metal's resistivity increases with increasing temperature.
Double the area means half the resistance. Resistance = resistivity times length / area. Resistivity is a property of the material only.
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 length, cross-sectional area, and resistivity. As resistivity changes with temperature, temperature indirectly affects resistance.
No. Resistivity is a material property, and is defined as the resistance for a piece of material of some standard size.
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.
Resistance (Ohms) = Voltage (v) / Current (I)
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.
