Between iron, copper, and aluminum, copper is the best, followed by aluminum, and last by iron. Gold is often plated over other metals because it is even better and resists corrosion.
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
No, brass is not the least conductive metal. It is a fairly good conductor of electricity, though not as conductive as metals like copper or silver.
Aluminum is the least reactive among sodium, aluminum, and magnesium. This is because aluminum is more stable due to the presence of a protective oxide layer on its surface, which prevents further reactions. Magnesium is more reactive than both sodium and aluminum.
Aluminum is rarely used in it pure form in common sheet. There is usually at least some silicon and copper as additives to control certain properties of the metal "mixture".
Silver has the least resistance among wood, iron, rubber, and silver. It is an excellent conductor of electricity and heat, making it have the lowest resistance.
Among lead, copper, zinc, and aluminum, aluminum has the highest ionization tendency because it requires the least amount of energy to remove an electron due to its low atomic size and high nuclear charge.

Lightning conductors do not contain radioactive compounds. They are typically made of metal, such as copper or aluminum, and work by providing a path of least resistance for the lightning strike to follow, directing the electrical discharge safely into the ground. There is no need for radioactive materials in a lightning conductor.
Yes, the best conductors have the least resistance.

While it would be nice if we had cable that had no resistance at all, the only materials that have no resistance are superconductors, and they only work at really, really, really low temperatures. There are some special applications where superconductors are used, but it is largly impracticle because of the cost of making the cable and of keeping it cold. We have a zillion miles of cable in the power grid and the wiring of structures. Most of it is copper. But copper is too heavy and of insufficient strength to use on the big high tension cross country cables hanging from those big towers. Also, aluminum is used in a lot of applications because it is cheaper than copper, though it isn't quite a good a conductor. If we use a slightly larger aluminum wire than the size of the correct size copper wire for a given application, the resistance of that bigger aluminum conductor will be about the same per foot as the smaller copper conductor. Copper is about the best we can do to make a conducting cable that is going to work at ambient temperature. Lastly, there aren't a lot of choices between good old copper and superconductors.
The length and the material that the conductor is made from. Different wire sizes have different ohm/foot. The longer the length of the conductor the higher the ohms/foot. Temperature also affects the resistance. Silver has the least resistance, followed by Copper, then Gold, then Aluminum. Here are some published resistances in micro ohm-cm: Silver - 1.6 Copper - 1.7 Gold - 2.2 Aluminum - 2.7
the best conductors with low resistance are silver, copper, gold, aluminum (best to least best)
Aluminum is the least reactive among sodium, aluminum, and magnesium. This is because aluminum is more stable due to the presence of a protective oxide layer on its surface, which prevents further reactions. Magnesium is more reactive than both sodium and aluminum.
A size 3/0 AWG copper main bonding jumper is typically required for service entrance conductors rated at 250 kcmil copper. This is based on NEC requirements for sizing the main bonding jumper to be at least 1/10th the circular mil area of the largest service entrance conductor.
