A conductor is a material which gives very little resistance to the flow of an electric current or thermal energy. … Silver is the best conductor because its electrons are freer to move than those of the other elements, thereby making it more suitable for the conduction of electricity and heat than any other element.
Why is silver a better conductor of electricity than copper?
The most electrically conductive element is silver, followed by copper and gold. Silver also has the highest thermal conductivity of any element and the highest light reflectance. … As to why silver is the best conductor, the answer is that its electrons are freer to move than those of the other elements.
Is silver the best electrical conductor?
Silver. The best conductor of electricity is pure silver, but to no surprise, it is not one of the most commonly used metals to conduct electricity. … The second drawback is the most obvious—it is simply too expensive to run silver wire through a building—far more expensive than aluminum or copper.
Which metal is the best conductor of electricity and why?
Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons) owing to the fact that gold has a preceding f-orbital from the actinide series.
Is silver the best conductor of heat?
Silver is an excellent conductor of heat, while stainless steel is a poor conductor. … Copper and gold are the only metals that come close to silver in thermal conductivity.
What are 5 good conductors?
Why silver is not used for making electric wires?
Though silver is a very good conductor of electricity but still that is not used in electric wiring primarily due to its cost. It’s very expensive compared to the widely used wiring material copper. Another reason for not using silver is that , it oxidizes easily and tarnishes when it comes in contact with air.
Is gold or silver a better conductor?
Gold conducts heat and electricity.
Copper and silver are the best conductors, but gold connections outlast both of them because they do not tarnish. It is not that the gold lasts longer, but that it remains conductive for a longer time. Gold is ductile: It can be drawn out into the thinnest wire.
Which is the bad conductor of electricity?
Difference between Good Conductor and Bad Conductor of Electricity
|Good Conductors||Bad Conductors|
|Example – Copper, Aluminium||Example – Rubber, Wood|
|Can be used to make electric circuits.||Can not be used to make electric circuits.|
Is Diamond a good conductor of electricity?
In a graphite molecule, one valence electron of each carbon atom remains free, Thus making graphite a good conductor of electricity. Whereas in diamond, they have no free mobile electron. Hence there won’t be flow of electrons That is the reason behind diamond are bad conductor electricity.
