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.

Why the electrical conductivity of material decreases with resistivity incrreasing?
As resistivity increases, it indicates that the material has more resistance to the flow of electricity. This increased resistance causes a decrease in electrical conductivity, as the electrons have a harder time moving through the material. In essence, higher resistivity hinders the ability of electrons to freely move and carry electrical current.
Would have the same resistance as a copper wire that is 4 m long and has a cross-sectional area of 0.066 cm2?
A wire with the same resistance as the given copper wire would have the same resistivity as copper. The resistance of a wire is dependent on its resistivity, length, and cross-sectional area. To calculate the resistance of a wire, use the formula R = (resistivity * length) / area; however, without the specific resistivity value, an exact value cannot be provided.
Do different materials have the same resistance?
No, different materials have different resistance values. Resistance depends on the material's electrical properties, such as its conductivity and resistivity. For example, metals generally have low resistance due to their high conductivity, while insulators have high resistance due to their low conductivity.
What does not affect electrical resistance?
Electrical resistance is primarily determined by the material's properties (resistivity, temperature, dimensions) and not affected by factors like voltage or current. However, the type of material, temperature, and length can impact resistance.
What kind of wire would have the greatest electrical resistance?
A thin and long wire made of a material with high resistivity, such as nichrome or tungsten, would have the greatest electrical resistance.
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
From copper and manganin which has higher resistance?
The question is actually wrong, they can both have the same resistance if configured differently, the real question should be which has a higher resistivity which is the electrical resistance found in a standard amount of each material. In this case Manganin has a higher resistivity than copper.
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.
What is resistivity of material?
the electrical resistance of a conductor through unit cross-sectional area per length is called "resistivity of material"
Does electrical resistance depend on temperature and bias voltage?
Electrical resistance depends on the temperature but not the biased voltage.AnswerIt's resistivity that can be affected by temperature, which means that resistance is indirectly affected by temperature.

What is formula of resistivity?
R is the electrical resistance,A is the cross-sectional area,l is the length of the piece of material.

No, different materials have different resistance values. Resistance depends on the material's electrical properties, such as its conductivity and resistivity. For example, metals generally have low resistance due to their high conductivity, while insulators have high resistance due to their low conductivity.
