Does a short thick metal wire or a long narrow metal wire have more resistance?

A long narrow metal wire would have more resistance compared to a short thick metal wire. Resistance is directly proportional to the length of the wire and inversely proportional to the cross-sectional area, so a longer wire with a smaller cross-sectional area will have higher resistance.


What is an Grade an answer to what affects the resistance in a wire?

*the resistivity of the metal the wire is made of *thickness of wire *length of wire


What is the torsion constant for the metal wire?

The torsion constant for a metal wire is a measure of its resistance to twisting. It is a physical property that describes how easily a wire can be twisted.


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.


Why does heating a metal wire affect its electrical resistance?

Heating a metal wire affects its electrical resistance because as the wire heats up, the atoms within the wire vibrate more vigorously, causing more collisions with the electrons flowing through the wire. This increased collision rate hinders the flow of electrons, leading to a higher resistance in the wire.


Does increasing the diameter of a metal wire decrease the electrical resistance?

Increasing the diameter of a metal wire typically decreases the electrical resistance. This is because a larger diameter provides more space for electrons to flow through, resulting in lower resistance.


Does heating a metal wire increase or decrease its electrical resistance?

it so increases it


What happens to the resistance of a copper wire when it is heated?

The resistance of a copper wire increases when it is heated. This is because heating the wire causes the metal ions to vibrate more, increasing collisions with the electrons and hindering the flow of current, therefore increasing resistance.


What would reduce resistance in a copper wire?

Reducing the temperature of the wire will decrease its resistance. Also, using a wire with a larger cross-sectional area will lower resistance since there is more room for electrons to flow. Finally, using a more conductive material than copper, such as silver, can reduce resistance.


Do bends in a wire effect its electrical resistance?

Yes, bends in a wire can increase its electrical resistance due to the deformation of the metal lattice structure, which interrupts the flow of electrons. This increased resistance can lead to energy losses in the form of heat.


What metal or material is used in the rear window defroster?

A High resistance wire, such as NiChrome; the wire heats up when amperage flows through.


Which wire has the lowest resistance?

Resistance is directly-proportional to the length and resistivity of a conductor, and inversely-proportional to its cross-sectional area. So a shorter wire would have less resistance than a longer wire made from the same material, and a wire with a greater cross-sectional area would have less resistance than one with a smaller cross-sectional area made from the same material. Resistivity depends on the material from which the wire is made, with some materials being better conductors than others. For example, silver has the lowest resistance compared with other metal conductors having identical dimensions. Similarly, a copper wire will have a lower resistance than an aluminium wire of identical dimensions.
