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 else can I help you with?
Is resistivity depends upon dimension of conductor?
Yes, resistivity is dependent on the material of the conductor, not its dimensions. Resistivity is an intrinsic property of a material that influences its ability to resist the flow of electrical current.
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.
What is the reason for such large variations in resistivity of different materials?
The resistivity of a material depends on its atomic and molecular structure, such as the arrangement of atoms and the number of free electrons. Materials with a highly ordered structure like metals tend to have low resistivity due to the easy flow of electrons, while materials with disordered structures like insulators have high resistivity because they impede the flow of electrons. Other factors like temperature and impurities can also affect resistivity.
Can electrons flow in conductors?
Yes, electrons can flow through conductors. Conductors are materials that allow the free flow of electric charge, such as electrons, due to their loosely bound electrons. This movement of electrons is what allows the flow of electric current in a conductor.
What is resistivity and what factor does it depend?
Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows the movement of electric charge. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is theohm⋅metre (Ω⋅m)It defined as resistance offerde by a unit length and cross section area conductor.It depends on material used.it depends on relexation time and 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
How does resistivity depends on temperature of conductors?
The resistance of a simple conductor normally rises as its temperature rises.
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.

Why gold is good conductor of electricity?
The conductivity (how well a material conducts) of a material depends on the density of its free electrons (number of free electrons per unit volume). The best metal conductor is silver. Copper's conductivity is 95% that of silver. Gold's conductivity is 65% that of silver. So, as you can see, gold is by no means the 'best' conductor.
What are the charateristics of a N-type silicon?
The current carrier is electrons in the conduction band. The exact resistivity depends inversely on the quantity of dopant.
Can electrons flow in conductors?
Yes, electrons can flow through conductors. Conductors are materials that allow the free flow of electric charge, such as electrons, due to their loosely bound electrons. This movement of electrons is what allows the flow of electric current in a conductor.

What is resistivity on what factor is depends?
Resistivity is a measure of a material's ability to resist the flow of electric current. It depends on factors such as the material's composition, temperature, and dimensions. Materials with high resistivity impede the flow of current more than those with low resistivity.
Five factors that affect resistance?
Electrical Resistance depends on three factors: Resistivity; Area; Length.Resistivity is the property of the matter. More Resistivity means more resistance.More Area means less resistance.More length means more resistance.R= Resistivity. Length/Area
