Why is copper used in making of electric wires when silver is the best conductor of electricity?
Surpassed only by silver, copper is a highly conductive metal. This means electricity can pass through it with greater ease, making it ideal for use in electrical wires. Unless they use silver, though, the high conductivity properties of copper allow for a greater distance of electrical current travel.
Why are electric wires not made of silver all the silver is the best conductor of electricity?
Ans: Though silver is a good conductor of heat but it is not used in making electric wire as it is very expensive . silver is a noble metal and it is used in making jewelry it is also used in electroplating and in making high Value coins that is why silver is not used in making electric wires.
Which is best electrical conductor copper or silver?
The metals are said to be good conductors of electricity if they allow electricity to flow through them easily….Answer: (2)
1 | Silver |

2 | Copper |
3 | Gold |

Why are silver good conductors of electricity?
“Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons). For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity.
Why is silver used over copper?
Although silver is a slightly better electrical conductor than copper (about 5\% better), it is currently over 8.9 times as expensive (using current spot market prices for each metal). Because the improvement in transformer efficiency is only slight, it is not cost effective to use silver windings instead of copper.
Is silver a good conductor of heat?
Silver is an excellent conductor of heat, while stainless steel is a poor conductor. In fact, silver is twice as good a conductor as aluminum, and nearly 10 times as good as a conductor as low-carbon steel. Copper and gold are the only metals that come close to silver in thermal conductivity.
Why silver is not used in electric wires?
Although silver is an excellent conductor of electricity, it is seldom utilised in electrical wiring due to its high cost. It’s a lot more costly than copper, which is the most used wire material. Another reason to avoid using silver is that it rapidly oxidises and tarnishes when exposed to air.
Why is silver the best conductor?
Why silver is a better conductor than copper?
Copper has the second highest thermal conductivity. Silver is a good conductor of heat than the copper because the electron can move more freely in silver as compared to the copper. The thermal conductivity of silver is higher than that of the copper.
Does silver or gold conduct electricity better?
Silver is the most conductive element. However, it is not often used to conduct electricity because it is more expensive than copper and tarnishes more readily than gold, particularly in environments that contain sulfur or ozone.
Is steel a bad conductor of electricity?
Similarly, the substances that have high electron mobility are known as good conductors. And, the ones which do not have good electron mobility are known as bad conductors or insulators. Metals like copper, gold, silver, steel, aluminium and brass and some of the most common and best conductor of electricity .
What materials are good conductors?
– Silver. Silver is the strongest conductor out of all known materials. – Copper. Copper is one of the most frequently used conductors due to its high conductivity combined with its relative abundance and low cost. – Aluminum. Along with copper, aluminum is another frequently used conductor. – Other Conducting Materials.
