Why electric wires made up of copper or aluminium?
Probably not. Both gold and aluminum have poorer conductivity than copper. If copper is rated at 100, then aluminum is 57 and gold is 65. Gold is sometimes used to electroplate electronic connectors, not so much because of is conductivity, but because it is so resistant to oxidation. Aluminum is a good choice where weight is a factor, such as in high-voltage transmission lines. Other than in a few special cases, copper is the better material for electrical wiring.
Is aluminum more conductive than copper?
Copper. Alloys of copper are used in most of the electrical wiring indoors and/or outdoors.However, aluminum is used in long-distance high-tension electrical lines because by weight it's a better conductor than copper is (and because it's less expensive and stronger). An aluminum wire needs to be thicker than a copper wire in order to have the same current-carrying capacity. However, even though it's thicker, it weighs less, which means the relatively expensive transmission towers can be spaced further apart without the wire sagging too much.
Why aluminum are use to produce electrical cables?
Aluminum is a metal that is a good conductor of electricity. It has an excellent ratio of conductivity/weight. Also has an excellent ratio of conductivity/price.
Why is aluminum useful?
Aluminium has a good 'strength to weight ratio'. This means that when you need to design something to have relatively little weight but be strong too, aluminum is a good choice.
Is aluminum wiring as good as copper wiring?
In general, no.Aluminum wiring has a higher resistance and therefore higher losses than copper.Aluminum wire connections must be carefully cleaned to remove oxides and a special anti-corrosion paste applied because of aluminum's reactivity with the oxygen in air. These oxides can cause a connection to overheat and fail, possibly causing a fire.For the same ampacity, aluminum wire must be larger in diameter, making for larger cables.There was a period where aluminum wire was used extensively when the price of copper was very high, but many of the aluminum installations were later retrofitted with copper for the above reasons.There are a few cases where aluminum is the better choice. High voltage transmission lines are usually aluminum with a steel or composite core. The higher losses are offset by the much lighter weight of the aluminum, allowing towers to be lighter and spaced much further apart, lowering costs.
Compare conductivity of iron copper and aluminum in terms of electricity.?
When compared by volume, copper is best, then aluminum and finally iron. When compared by weight, aluminum is better than copper. You have to compare by volume because aluminum is so much lighter than copper, an aluminum wire that weighed the same as a copper wire would be much bigger and harder to work with.

Is copper an electrical conductor?
Yes, Because they have a large number of free electrons. Having lots of free electrons makes it easier to nudge the electrons around, thus creating electric current. The best conductors are silver, copper, gold and aluminum respectively. Cost, weight and ease of handling dictate using copper or aluminum as conductors in most industries. Also it is used in piping as it is unreactive with water.
What sized of copper cable to replaced 240 square millimeter aluminium cable?
Copper is a better conductor by weight, but aluminum is better by weight, so the copper will be thinner but heavier. You will see that a 250 kcmil aluminium wire will get you 170 amps at 60 degC while a 000 (or 3/0) copper wire will get you 165 amps at 60 degC. I think you mean circular mils, not square millimeters.

Why is electrical cable made of copper?
Electrical cables are made from copper because it is a better conductor than aluminium, it is also cheaper. If you did use aluminium then;it may set fire.may oxidize after a while and over heat.I hope this helped! :D
Why do they make tennis rackets out of aluminum?
Aluminum is durable. It is also light weight compared to other materials such as wood.
Why are power cables made from iron and aluminium?
#1 Primarily because of its lighter weight. Copper is a better conductor, but is too heavy and more expensive. #2 Aluminium is lighter than most other metals yet still strong enough to carry its weight, so the cables do not need to be monstrously thick, and it is a fairly highly conductive material (being a metal) so power is not wasted on the transmission. It should be noted, however, that aluminum by itself is not normally used for long spans, i.e. high-voltage power transmission. It is wrapped around a steel core. The steel is used for strength, and the aluminum is used for better conductivity. Such cable is called type ACSR (short for aluminum conductor - steel reinforced). #3 Because of its light weight. It is great at conducting a current and copper is expensive. #4 Because of conductivity.
Which has the greater density 5kg of lead or 10kg of aluminum?
Lead will always have the greater density compared to aluminium. The weight only influences the volume in question. 10kg of Al will be much more(bigger in size) than 5kg of lead.
Which metals are the best conductor of electric?
If the volume and length of the wire are constant, then silver. If the weight and length of the wire are constant, then sodium is the best conductor.
How are a copper wire and aluminum foil alike?
negative charges can't move through them
