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.

What three factors affect the resistance in a circuit?
The three main factors that affect resistance in a circuit are the material the wire is made of, the length of the wire, and the cross-sectional area of the wire. Other factors, such as temperature and temperature coefficient of resistance, can also impact resistance.
What are the three factors that would give a piece of copper wire high resistance?
High resistance in a copper wire can be caused by factors like a longer wire length, a thinner wire diameter, and the material's high temperature, which increases resistance due to increased collisions among electrons.
What three things affect the resistance in a wire?
The three main factors that affect the resistance in a wire are the material of the wire (different materials have different resistivities), the length of the wire (longer wires have higher resistance), and the cross-sectional area of the wire (thicker wires have lower resistance).
What three factors affect the amount of air esistance on an object?
The three factors that affect the amount of air resistance on an object are the object's speed (faster speed leads to higher air resistance), the object's size and shape (larger or less streamlined shapes experience higher air resistance), and the air density (higher air density increases air resistance).
What three factors affect the amount of air resistance acting on a object?
The factors that affect the amount of air resistance acting on an object are the speed of the object, the surface area exposed to the air, and the shape of the object. A faster object experiences more air resistance than a slower one, a larger surface area increases air resistance, and a streamlined shape reduces air resistance.

Why is electrical resistivity important to a design engineer?
electrical resistance increases current flow decreases.so to know the current flow in the network ,electrical resistance is required.AnswerResistivity is important, because it is one of the three factors that affect the resistance of a material. The other factors are the length and cross-sectional area of the material.

1. Heavy, 2. Expensive, 3. Resistance.
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
