Can you use an aluminium wire instead of copper for a simple electrical circuit?

Yes, you can use an aluminum wire. Aluminum does conduct electricity. However, there is a well-known problem with aluminum wire. When exposed to air, the outer layer of aluminum forms a non-conductive oxide. There is resistance to the flow of electricity as it attempts to get through the aluminum oxide coating to the conductive aluminum below. When aluminum wire is used to reduce weight, it is usually welded to another metal that makes a better contact, such as copper. The contact metal is then what is connected.


Is the earth also like a giant battery?

No. Electricity pylons (usually called "transmission towers" in the US) are basically just supports for the wires. They are specifically designed to be insulated from the electricity flowing through the wires.


What color is aluminum?

Bulk aluminum is usually a silver color. (Think aluminum foil.)


How do you name AlCl3?

The correct name for AlCl3 is aluminum chloride. This is a compound made from chlorine and aluminum. It is usually a white or yellow salt-like inorganic compound.


What the metals is the most suitable for vehicles?

Kinda obvious :S Metals (usually aluminum or steel) are used in cars because they are strong and cheap. Expensive sports cars usually have stronger metals (like titanium) but that makes them more expensive. Different metals are used for different purposes, too. The main frame of a car would usually be steel instead of aluminum because it is stronger but delicate pieces would be made of aluminum because strength is not needed but it would be cheaper to make them in aluminum

Why do copper or aluminum wires generally used for electrical transmission and distribution purposes?

Both metals have a low resistance to conductivity. They are extremely flexible and do not degrade under electrical transmission as do other metals. They are less expensive than the best conductors, silver and gold.


Is a transmission considered scrap metal?

Yes, a transmission is considered scrap metal! You can sell it to a scrap yard if you wish. They are usually made of some kind of aluminum.

What matrieal that conduct electricity?

Usually Metallic substances conduct electricity and heat- They are good conductors of heat because solid particles are close to each other and vibrate frequently. The properties of metals are shiny usually hard and perpetual- some have special attributes such as aluminum which is light and fairly strong.


What is beer can made up of?

Usually aluminum, steel or wood.


How do you convince your family school or community to recycled aluminum cans?

People are far more likely to recycle if a recycling container is conveniently located where they usually consume their beverages, especially if they don't have to empty it. It might also help to inform them that it takes a tremendous amount of electricity to separate aluminum from bauxite, the ore in which aluminum exists in nature. Much, much less energy is needed to recover aluminum from existing aluminum products, like cans.
