How many amps will taken by 1sq mm alluminium wire?
1 mm2 aluminium wire is not easy to buy but 1 mm2 copper wire is rated at 10 amps. Since the conductivity of aluminium is 7/12 that of copper, 1 mm2 aluminium wire would be rated at 7½ amps max (the same amount of heat is produced per metre by a current of sqrt(7/12) times that for copper).
What metals does the US use to make quarters?
Since 1965, U.S. quarters have been made of a solid copper core with a copper/nickel coating.
Is the element aluminium lustre?
The question isn't clear since the word "lustre" means "shine". If the question is, "Does the element aluminum lustre?", then the answer is yes, because metals in general are shiny.
Is a nickel a good conductor?
Its OK: most metals are good conductors -------------------------------------------- More: since a nickel is made out of copper and nickel then it is sure to be a good conductor. ------------------------------------------------------------------------ More Information: Pure nickel is not a very good thermal conductor compared to other metals like copper. Nickel is often mixed with other metals, such as copper, and those alloys often have better thermal conductivity than pure nickel.

What 2 metals are nickels primarily made of?
US nickels are made of an alloy of 25% nickel and 75% copper. Since 2000, most Canadian nickels have been made of a steel/copper alloy plated with nickel.
Is Hydrogen produced when Magnesium reacts with copper sulfate solution?
The activity series of metals goes something like this: Lithium Potassium Barium Calcium Sodium Magnesium Aluminum Zinc Iron Nickel Tin Lead Hydrogen Copper Mercury .............and so on..... ps, I might have left some elements out....can't remember them all... Since magnesium is higher in the reactivity series of metals, it can replace copper in a reaction. Copper is lower in the activity series of metals therefore can not replace magnesium.
Why is aluminium used in the central core in power cables?
Aluminum is used in the central core of power cables because of its lightweight and good conductivity properties, making it more cost-effective than copper. Additionally, aluminum is less prone to theft due to its lower scrap value compared to copper.
What will be the color when you dip litmus into aluminium oxide?
Aluminium oxide does not have any effect on litmus paper. Litmus paper is typically used to test for acidic or basic substances, and since aluminium oxide is a neutral compound, it will not cause any color change in the litmus paper.
What is an example of a an electrical insulator aluminum silver paper or copper?
Of aluminium, silver, paper or copper, only (very dry) paper is an insulator - the thicker the better.
Why would your skin color change to green?
Copper has a reaction with skin that may turn it green or black. So if you have gold or silver jewelery since copper is one of the metals in these 2 to keep prices down this may be the most likely cause.
Which metals do not attract magnets?
The only element attracted to magnets is iron. If a magnet sticks to it, it contains iron. Since steel is mostly iron, it attracts to magnets as well. Gold, silver, titanium, platinum, copper, and aluminum are metals that don't attract to magnets, just to name a few.
