The resistance of a wire depends on the?
The length, cross-sectional area, and resistivity. As resistivity changes with temperature, temperature indirectly affects resistance.
What is the resistance of a 3.5 m length of copper wire 1.5 mm in diameter?
Resistivity of Copper = 1.68x10^-8 radius of wire = 1.7x10^-3m/2 = 8.5x10^-4 A =pi*(8.5x10^-4)^2 = 2.310^-6m^2 Plugging in the numbers: R = 2.6x10^-2 = .026 Ohms
Is a copper wire a ground wire?
Yes, if it is not an insulated wire. If it is bare copper it is always ground. But the hot and neutral wire are also copper, they are just insulated.
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.
Can you use copper wire instead of eureka wire in finding its resistivity?
Yes, you can use copper wire instead of eureka wire to determine resistivity by measuring its resistance, length, and cross-sectional area. However, keep in mind that the resistivity values for copper will be different from eureka wire, so you will need to account for that difference in your calculations.

Can copper and alluminium wire of same length and diameter have same resistance?
No, copper and aluminum wire of the same length and diameter will not have the same resistance. Copper has a lower resistivity than aluminum, so a copper wire will have lower resistance compared to an aluminum wire of the same length and diameter.
Why is copper wire the best known conductor?
The best electrical conductor known is silver, not copper. Electrical resistivity of silver: 1,59.10-8 ohm.m Electrical resistivity of copper: 1,68.10-8 ohm.m A good electrical conductor has a very low electrical resistivity and a high electrical conductivity (the same principles for the thermal conductivity).
Which physical properties of copper wire are independent of the amount of matter?
Physical properties of copper wire that are independent of the amount of matter include conductivity, resistivity, melting point, and thermal expansion coefficient. These properties remain constant regardless of the quantity of copper wire present.
When An aluminum wire 5m long and 2mm diameter is connected in parallel with 3 m long the total current is 4A and that in the aluminum wire 2.5A find the diameter of the copper wire the respective 1.7?
Using the formula for resistance of a wire (R = ρ * (L/A)), we can find the resistivity ratio (ρ_aluminum / ρ_copper) as 1.7 since the total current in both wires is the same and the lengths are different. Knowing that the resistivity of copper is 1.7 times less than that of aluminum, and given that resistivity is inversely proportional to cross-sectional area, the diameter of the copper wire will be √(1.7) = 1.3 times the diameter of the aluminum wire. Since the diameter of the aluminum wire is 2mm, the diameter of the copper wire will be 2mm * 1.3 = 2.6mm.
Does a thin wire has more RESISTIVITy or a thin wire of the same material?
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.
If the diameter of wire is double what is resestivity?
Resistivity won't change. Resistivity is a material property that doesn't depend on the shape.
Three factors that affect the resistance of a copper wire -?
There are three main factors that affect the resistance of a copper wire: Length of the wire: The resistance of a wire is directly proportional to its length. As the length of the wire increases, the resistance also increases. This is because the longer the wire, the more obstacles (collisions with electrons) the current has to overcome, resulting in higher resistance. Cross-sectional area of the wire: The resistance of a wire is inversely proportional to its cross-sectional area. As the cross-sectional area of the wire increases, the resistance decreases. This is because a larger cross-sectional area provides more space for the flow of electrons, reducing the resistance. Resistivity of the material: The resistance of a wire is also dependent on the resistivity of the material it is made of. Resistivity is an inherent property of the material and is a measure of how much the material opposes the flow of electric current. Copper has a relatively low resistivity compared to other metals, making it a good conductor and suitable for wiring applications. The relationship between these factors and the resistance of a copper wire can be expressed by the formula: R = ρ × (L / A) Where: R is the resistance of the wire ρ (rho) is the resistivity of the material (in this case, copper) L is the length of the wire A is the cross-sectional area of the wire By adjusting these three factors, you can control and manipulate the resistance of a copper wire to suit your specific needs in electrical and electronic applications.
