Which Metal Is The Best Conductor Of Electricity?

If by "best conductor" you mean which metal has the highest conductivity, then the answer is silver. Its conductivity at 20 degrees centigrade is 63000000 seimens per meter (the unit of conductivity). However, copper is much cheaper than silver so it is commonly used for a lot of wiring. Gold is another very good conductor, it is used because it does not oxidize (since it is a stable element) so it is great at the end of connectors which are exposed to the air for long periods of time. Of course, gold is expensive so it is only used where copper or silver are not ideal. There is a table on Wikipedia showing the resistivity for a large number of metals. Resistivity is more commonly used as it is often important to calculate the resistance that a given length of wire will have to any current flowing through it. To find the conductivity, use the formula: Conductivity = 1/resistivity. For example, copper has a resistivity of 1.68?10-8 so its conductivity = 1/1.68*10-8 which is 5.95*10-7

Jesus, the people that answer these things are idiots.

Silver

Silver

It is silver.

The correct answer is silver

Silver

Silver has the highest electrical conductivity of any element. Copper is second and is much cheaper, and therefore more widely used. Gold is an excellent conductor and is very stable, and therefore widely used for connectors.

The best conductor  of electricity is silver, but gold is used more often because it doesn't oxidize.  

Thank You.

Silver....

Gold and platinum are the most reliable but its to expensive so must people use copper and aluminium

Well loads of sorts of metal! But the est are gold, platinum are the most reliable but way to expensive so 3rd and 4th are copper and aluminium!

It depends on how you are measuring conductivity: By volume or weight. Most conductors used for the transmission and distribution of electricity are copper or aluminum. Copper has better conductivity on a volume basis, while aluminum has better conductivity on a weight basis.

Carbon

Well, lets just say that the metal that is magnetic.

That would be gold. But copper is a lot cheaper.

Da copper
cause is a coinage metal,

I do think iron
