Wires are made of many metals (and even non-metals). Field telephone wires for military use are steel. The Electric Company uses more aluminum than copper. Silver is the best conductor. Gold is used to wire integrated circuits because it does not corrode.
No, copper wire is not magnetic.
A thicker copper wire will have higher resistance as it will offer more opposition to the flow of electrons compared to a thinner wire. Additionally, a longer copper wire will have higher resistance compared to a shorter wire due to increased distance for the electrons to travel. Finally, a copper wire with impurities or defects will have higher resistance than a pure copper wire.
A copper wire will sink in water because copper is denser than water.
No, copper and aluminum wire of the same length and diameter will not have the same resistance. Copper has a lower resistivity than aluminum, so a copper wire will have lower resistance compared to an aluminum wire of the same length and diameter.
The dependent variables in a copper wire resistance experiment would typically be the resistance of the copper wire being measured. This would vary based on factors like the length and thickness of the wire, as well as the temperature.
Yes
depends on the content of the copper wire, if its 100% usually it will
Copper is more stronger against other metals.
It can be used for pennies, copper wire and many other uses

The primary element in a copper wire is copper itself, which can range from 99.9% to 99.999% pure. Copper wires are often also alloyed with other elements such as tin or silver to improve their properties like strength and conductivity. Insulation materials like PVC or nylon are also used around the copper wire to protect and insulate it.

how much copper is in copper wire
Bending a copper wire is a physical change because the copper itself does not undergo a chemical reaction. The arrangement of copper atoms simply changes temporarily when the wire is bent, but the properties of copper remain the same.
No. Copper wire is a solid
No.. Copper wire isn't
No, copper wire is not magnetic.
