What are the two factors of a wire that will alter its resistance?
The resistance of the wire is directly proportional to the length and inversely proportional to the area of cross section. Also it depends on the material of the wire with which it is made. So three factors. Length, area of cross section, material.
If you cut a wire what happend to resistance?
If you are talking about the total resistance in a circuit , it depends on the components in the circuit and the location of the cut.If you are talking about a single wire, the resistance becomes infinite (or close to it) when the wire is cut.
Does a short copper wire have more resistance then a long one?
No. Other things being equal, a long wire has more resistance than a short wire.
How does wire thickness affects resistance?
Increasing wire thickness decreases its resistance, while increasing its length increases its resistance. Provided the voltage between the ends of the wire is constant, the current through it is inversely proportional to its resistance.
Does thin wires have high or low resistance?
Other things being equal, a thin wire will have a higher resistance than a thick wire.
Electrical resistance in a wire depends on the wire's?
It's dependent on the wire's composition. That is, what material it is made of. <<>> The electrical resistance in a wire depends on the wire's length and cross sectional area.

What is the resistance of metal wire?
the resistance is depends on the type of the metal and ith length
Does the diameter of the wire affect resistance?
Yes. Other things being equal, a thicker wire has less resistance.
What is a fundamental property of a wire that depends on a wire's moleculal structure and size?
Resistance

Will a short thick metal wire have better resistance compared to a long narrow metal wire?
"Better" depends on how much resistance you need for your circuit design.A short thick wire will have less resistance than a long thin wire of the same substance.Whether that's better or worse depends on how you plan to use the wire.

Other things being equal, a thin wire will have a higher resistance than a thick wire.

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
Three ways which resistance of a wire can be increased?
You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).
