If the specific heat of aluminum is 0.902 and the specific heat of copper is 0.268 what makes copper a better choice to use for hot water lines in your house?
This means that copper will not absorb the heat from the water as much as the aluminum. Aluminum will "steal" more heat from the water- which you do not want. You need the heat to stay with the water until it serves its purpose.
What are the advantages of using copper compared to aluminium for transmission lines?
Copper is a better conductor than aluminum. Two wires with the same cross-sectional area, or any two constructs with the same physical shape and size, one fabricated from aluminum and the other from copper, the one made of aluminum always has higher ohmic resistance.
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.
What are overhead power lines made of?
Mostly aluminum because they are ran in free air and that changes their ampacity rating enough for aluminum to be more economical than copper. Gold has a higher ampacity rating than either al. or copper but it is to valuable to leave hanging in the air.
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 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.
What does aluminum foil do to electricity?
Aluminum is a good conductor of electricity. While it won't actively "do" anything to electricity, it will pass electric current if it used as part of a circuit. Aluminum is used in overhead power transmission lines as it is lighter than an equivalent copper conductor.
What are some products that are made from Electrical Wires?
The three most popular wire materials are copper, aluminum, and silver. Aluminum is very low cost and is used in high power lines along roads for mass transportation of electricity. Copper is more expensive and a better conductor than aluminum, and is found commonly in residential homes and electronic devices. Silver is one of the best metals for conductivity, but also very expensive. It is used in high end electronics, mostly hi-fi audio gear and computer connections.
Solder copper lines on air conditioner?
on air conditioners you silver braze the copper lines
Why aluminium is used in electrical wires even then it is corrosive metal?
Aluminum is used in electrical wires as it is a good conductor, is lightweight and inexpensive (as compared to it's closest competitor copper). Most power distribution lines, especially overhead ones, are aluminum.
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
What type of pipes are best for the kitchen?
A copper pipe is the preferred choice of many plumbers for water lines. A PVC pipe is very versatile also though, and is another favorite amongst plumbers when dealing with water lines.
