What else can I help you with?
Which wire would have the lowest resistance a long thin iron wire at a high temperature or a short thick copper wire at a low temperature?
The short thick copper wire at a low temperature would have the lowest resistance. Copper has lower electrical resistance than iron, and a shorter, thicker wire has lower resistance compared to a long thin wire, regardless of the temperature.
What is the predominant carrier of electrical charge in a copper wire?
The predominant carrier of electrical charge in a copper wire is the free electrons within the copper atoms. These free electrons are able to move easily through the lattice structure of the copper, allowing for the flow of electric current.
Why is copper wire better conductor of electricity than a rubber tube is?
In rubber electrons cannot freely move among atoms as in copper.
Dose recycled copper wire be come new copper wire?
Copper wire sent for recycling is remelted and rerefined. It becomes a new copper product one of which might be new copper wire.
What is the difference between stranded copper and tinseld copper wire?
bare copper is pure copper, while tinned copper is having light coating of Tin over it, preferred where soldering phenomenon is req. while the bare copper is good conductor then tinned copper.
What is it called when copper is pulled into thin wires?
When copper is pulled into thin wires, it is called copper wire drawing. This process involves passing the copper through a series of decreasing diameter dies to gradually reduce its diameter and form a thin wire.
Meaning of wire?
Wire is a metal that is made so thin it can be bent. There are many types of wire including, copper, aluminum and gold.
How many atoms are in a 1cm of copper wire and who calculate this?
The number of atoms in a 1cm length of copper wire can be calculated using Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. The molar mass of copper is around 63.55 g/mol, so you would find the mass of copper in 1 cm of wire and then convert that to moles to determine the number of atoms.
How many electrons in copper wire?
Copper wire typically contains one free electron per atom, as copper has one electron in its outer energy level. So, the number of electrons in copper wire depends on the number of copper atoms present in the wire.
What Is A Twenty-Two Gauge Metal Wire?
A rather thin copper or aluminum wire.
What property of copper allows it to be pulled into thin wire?
Copper's high malleability and ductility allow it to be pulled into thin wire. These properties mean that copper can be easily stretched and shaped without breaking, making it an ideal material for wire production.
Is a wire a solid?
This just means a wire with a solid central core, ie made from one solid length of copper or aluminium, as opposed to a wire made from many thin strands
What is a solid wire?

What is tinned copper wire?
Tinned copper wire is copper wire that has been coated with a thin layer of tin. This coating helps to prevent oxidation and corrosion, making the wire more durable and long-lasting. It is commonly used in electrical applications and soldering.
Is copper wire a mechanical mixture?
It should be a "pure" substance, but its really an alloy.
Is copper wire a pure substance mechanical mixture or a solution?
Copper wire is a pure substance, as it is made entirely of copper atoms.
Which wire would have the lowest resistance a long thin iron wire at a high temperature or a short thick copper wire at a low temperature?
The short thick copper wire at a low temperature would have the lowest resistance. Copper has lower electrical resistance than iron, and a shorter, thicker wire has lower resistance compared to a long thin wire, regardless of the temperature.
