If the wire's cross-section area is constant, then its resistance per unit length is constant, and the total resistance should be directly proportional to the length of a wire segment.

The resistance of a wire increases as its length increases. This is because as the length of the wire increases, there are more atoms for the electrons to collide with as they pass through the wire, leading to more opposition to the flow of electric current and a higher resistance.

A lenght of cirular wire as a resistance of 1 ohms if its the diameter was double its resistance woul be.?
If the diameter of the circular wire is doubled, the resistance will decrease by a factor of four, resulting in a resistance of 0.25 ohms. Resistance is inversely proportional to the cross-sectional area of the wire, which is affected by the diameter.
How does the resistance of a wire vary with its length?
The resistance of a wire is directly proportional to its length. This means that as the length of the wire increases, the resistance also increases. This relationship is described by the formula R = ρ * (L/A), where R is resistance, ρ is the resistivity of the material, L is the length of the wire, and A is its cross-sectional area.
How does the resistance of a wire vary with its diameter?
At a greater diameter, the cross-section will also be greater, and therefore the resistance will be less. This assumes that other things are equal, of course.
What happens to resistance of the wire if the wire is short?
If the wire is short, its resistance will likely decrease. A shorter wire has less length for electrons to travel through, resulting in lower resistance according to the formula R = ρL/A, where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
How does length affect resistance of a wire?
In general, the longer the wire, the greater the resistance. This is because a longer wire offers more resistance to the flow of electrons compared to a shorter wire. The resistance of a wire is directly proportional to its length.

How would you find out the length of the wire effects the voltage drop across the wire when the current passing is kept constant?
A: There are tables that qualify IR drops for wire lenght. All wire do offer resistance to current this current will cause directly a volatge drop according to the wire resistance so it can be measured to find the IR drop

How does the thickness of the wire affect resistance?
A thicker wire has less resistance than a thinner wire.
How does the thickness of wire affect the resistance?
Thicker wire has less resistance than thinner wire due to lower electrical resistance. Thicker wire allows more electrons to flow through it easily, resulting in less opposition to the flow of electric current.
Which has greater resistance a thick wire or a thin wire of the same lenght?
The thin wire has more resistance to the flow of electric current than the thick wire. If you connect the wires to a battery the battery will supply electrical pressure (voltage) and the wires serve similar to pipes that conduct water under pressure. A small pipe exhibits more resistance to the flow of water and a thin wire exhibits more resistance to the flow of electrons. However, as you point out different wire materials exhibit different resistances for equal sizes (silver conducts better than copper, etc.).
When wire is thicker its resistance is?
When a wire is made thicker it's resistance decreases.
How does length affect resistance of a wire?
In general, the longer the wire, the greater the resistance. This is because a longer wire offers more resistance to the flow of electrons compared to a shorter wire. The resistance of a wire is directly proportional to its length.
When a wire is made thicker it resistance?
When a wire is made thicker it's resistance decreases.
Why is electricity related to voltage?
Because voltage is the power that makes electricity to circulate in a wire. Depending on the diameter, the lenght and material of the conductor (wire) the current, (the amount of electrons) flowing in the wire, the resistance will be lower or higher. Conclusively, the voltage is not the electricity itself, but it is like a pump that impulses the water through a pipe. Electricity is the current whose unit of measurement is the Ampere. So you have the voltage, resistance, and current in a electrical circuit on a direct current system.
