If Iron conducts eleticity long distances better than any other metal then that would be one reason.
How to calculate iron losses in dc machine
The live (blue) wire delivers the power from the mains into the iron's circuit. The neutral (brown) is the return path back to the mains (electricity needs a closed circuit to flow). The earth (green/yellow stripe) wire is a safety device in case anything goes wrong with the wiring in the iron to cause a short circuit. It delivers the power along the earth wire into the ground instead of it going through the user.The Iron would work without the earth wire being connected but the user would be at risk of electric shock if the iron developed a fault or the wires came loose.
100%. It not practically possible to achieve 100% though. There are iron and copper losses even if it is not loaded.
A: Absolutely a power transfer will have an internal loss of IR . for a power transformer the loss can be as much of 20% or more if other magnetics are involved like iron screw holding the lamination together. Usually brass is used to reduce that loss.
An iron nail can replace a short length of wire in a circuit if the points of contact of the nail to the rest of the circuit have no rust or corrosion and good connection can be made. Using solder to join the nail to the circuit can help make a good connection. However, if this is for a scientifically controlled experiment fine as long as its very low voltage. If you are considering high voltage . DO NOT ATTEMPT IT. Its extremely dangerous
Not ideally. A 9 wood would replace a 5 iron, but could be used to replace a 6 iron if you so wanted.
Maybe...iron would replace aluminium to form iron sulphate. iron+aluminum sulfate--->iron sulphate+aluminium.
There ARE no magnetic lines of force. The magnet and iron filings demonstration causes the illusion of lines, but if you take a picture of the "lines" and replace the paper and iron filings, the "lines" will appear in a different place. But if there WERE lines of force they probably could exist in vacuum.
Check the socket for power Check the cord Check the removable tip Replace tip Buy a more powerful iron.
Yes. Zinc will likely replace iron because it is more reactive.
Poison
The way I would do it is iron it. You can still the the wrinkled lines, but its flat.
Iron is iron . . . but rails are made of high-strength steel. (Which is made from iron.)
to replace a 3 iron or 4 iron
yes
Magnets.
Telephone lines are made of iron or steel. Between the iron or steel core and the pipe is an insulating material. All Telephone lines are made and work this way.
