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.

because resistance is directly propotional to the length of the conductor

A lenght of cirular wire as a resistance of 1 ohms if its the diameter was double its resistance woul be.?

Its resistance would be half , 0.5 ohms is the answer.


How does the resistance of a wire vary with its length?

resistance of wire increases with increases of 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


What happens to resistance of the wire if the wire is short?

Short wire has less resistance Long wire has more resistance Thick wire has less resistance Thin wire has more resistance


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.


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?

A thicker wire has less resistance than a thinner wire.


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. The only time that this is not so is when the wire is a superconductor, in which case the resistance is always zero.


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.
