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.
How does a resistivity of a conductor depends upon number density n of a free electrons?
The resistivity of a conductor is inversely proportional to the number density (n) of free electrons. This means that as the number density of free electrons increases, the resistivity of the conductor decreases, and vice versa. This relationship is due to the fact that more free electrons provide more paths for the flow of electric current, resulting in lower resistance.
What is the Difference between reluctance and resistivity?
Reluctance is a measure of how much a magnetic circuit resists the flow of magnetic flux, while resistivity is a measure of a material's resistance to the flow of electric current. Reluctance is commonly used in magnetic circuits, while resistivity is used in electrical circuits.
Is resistivity of a material depends upon the dimensions of a material?
Resistivity is an intrinsic property of a material and is not affected by the dimensions of the material. Resistivity is determined by the material's composition and structure. The resistivity of a material remains constant as long as the material is uniform.
Is a nail a good conductor of electricity?
Yes, a nail is a good conductor of electricity because it is made of metal, which contains free electrons that can easily move and carry electric current. This makes nails commonly used in electrical applications.

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.
What is the Difference between reluctance and resistivity?
Reluctance is a measure of how much a magnetic circuit resists the flow of magnetic flux, while resistivity is a measure of a material's resistance to the flow of electric current. Reluctance is commonly used in magnetic circuits, while resistivity is used in electrical circuits.

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.
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.
