What is the interior of an electrical wire made of?
Copper or aluminum.
If wire delivering a certain amount of current is made narrower, the resistance of the wire will increase. This will limit current, and the wire will warm up some. If the wire is made shorter, resistance will decrease. The electrical codes have well published limits on the amount of current different types of wire can carry.
Electrical wire is the medium through which electricity is carried to and through each individual home that uses electrical power. It is made of a metal that easily conducts electricity, usuallycopper, in a plastic sheath called an insulator. There are various different types of this wire, each suited to certain loads and conditions.
Aluminum is an extremely conductive material. Electrical wire is commonly made of aluminum. Aluminum foil is just a big block of aluminum flattened into a long roll. SO THE ANSWER IS ALUMINUM CAN CONDUCT ELECTRICITY!!!!!!! In the US aluminum electrical wire is banned, because the surface oxide is nonconductive causing high resistance connections to develop resulting in electrical fires. Only copper electrical wire is legal, its surface oxide is conductive.
Electrical resistance of a wire is the opposition of the flow of electricity through the wire. There are several factors that determine the electrical resistance of a wire. One factor is what material(s) the wire made up of. If there is two wires of equal dimensions, and if one wire is made of pure golf while the other is made of lead, then the wire of Gold will have less resistance. Another factor that effects…
Any conductor (wire for example) which has an electrical current flowing through it will develop a magnetic field around it because the atoms are being stressed in a particular direction. When that wire is made into a coil shape; the magnetic effect is concentrated, even strong enough to do work. How much work depends on the wire size, electrical source, and how well the coil was made.
There are many substances that would make a great electrical wire. Golds is good. It is easy to work. Silver works well and could be extruded like copper or aluminum the more commonly used metals in electrical wire. All of these substances have a common element of pliability. That is they are easily made into wire, they bend and carry electricity well.
