Is resistivity depends upon dimension of conductor?
no its depends on material properties.
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.
Is resistivity of a material depends upon the dimensions of a material?
No. Resistivity is a property of the material itself and does not change no matter how much of that material you have. Resistance, however, does depend on the dimensions of the material.
Is a nail a good conductor of electricity?
It entirely depends upon what metal, or more likely metal compound, the nail is made out of. However, as with anything made of metal, you can be fairly sure it will be a good conductor of electricity no matter what it's made from.

What are the four factorws affecting electrical resistance?
There are really only three things that affect electrical resistance. They are the length and cross-sectional area of a conductor and its resistivity. However, resistivity depends not only on the material from which the conductor is manufactured, but upon its temperature. So you could say that temperature indirectly affects resistance via its resistivity.
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.
Is resistivity of a material depends upon the dimensions of a material?
No. Resistivity is a property of the material itself and does not change no matter how much of that material you have. Resistance, however, does depend on the dimensions of the material.
Do resistivity depend upon area of crosss-section?
No. Resistance does.
How many ohms does a 9v produce?
Question is not clear.Is question asking about the battery's internal resistance ?AnswerResistance is not affected by voltage. The resistance of a material depends upon the length, cross-sectional area, and resistivity of that material. As resistivity is affected by temperature, resistance is also indirectly affected by temperature.
Can arc explosions cause electrical shock?
Depends upon the source/cause of explosion and your contact at that moment with conductor of electricity.
Does resistance depends upon the dimension?
The basic relation to calculate resistance tells us: R = rho*l/A with R = resistance [Ohm] rho = resistivity [Ohm*meter] l = length [m] A = surface area [m^2] So, the resistance (given a certain resistive material) merely depends on the ratio between the length and the surface area of a resistor. Resisotrs tend to be bigger if they have to dissipate more power, for mor heat needs to be lost.
Is a nail a good conductor of electricity?
It entirely depends upon what metal, or more likely metal compound, the nail is made out of. However, as with anything made of metal, you can be fairly sure it will be a good conductor of electricity no matter what it's made from.
The magnitude of the resistance of a wire depends on?
Temperature, Length of wire, Area of the cross-section of wire and nature of the material.
How is resistance effected by frequency?
Resistance isn't directly affected by frequency -rather, it depends upon the cross-sectional area, length, and resistivity of a conductor.Having said that, at higher frequencies, current tends to flow towards the surface of a conductor. This is called skin effect, and acts to reduce the effective cross-sectional area of a conductor -resulting in the resistance of that conductor rising somewhat. The higher the frequency, the greater the skin effect, and the higher the resistance.This higher resistance to the flow of AC current is termed AC resistance, and shouldn't be confused with a circuit's reactance which is something entirely different.Additional answer:The skin depth is that distance below the surface of a conductor where the current density has diminished to 1/e of its value at the surface.
