Due to the nature of materials it affects the flow of current. Both iron and mercury are metals and considered as conductors of electricity. But iron is a better conductor than mercury.
Which is a poor conductor of heat mercury or lead?
The correct answer is Lead. Among metals: Mercury metal is a poor conductor while Lead is the poorest conductor.
Although lead compounds can be good insulators, pure lead is a metal that conducts electricity, making it a poor insulator. It sees use in electrical contacts because, being a relatively soft metal, it deforms easily when tightened and makes a solid connection.
Is lead poor conductor?
Lead is a poor conductor of heat because it readily reacts with the atmosphere to form lead oxide, where we know metal oxides are poor conductors of heat and electricity as well.
Among iron and mercury which is a better conductor of electricity and why? Answer: Iron is a better conductor of electricity than mercury because the resistivity of mercury is more than the resistivity of iron.
Which metal is best conductor?
Silver: The single most conductive metal, silver conducts heat and electricity efficiently thanks to its unique crystal structure and single valence electron.
What is the poorest conductor of electricity?
Bismuth and tungsten are two metals which are poor conductors of electricity. Dear friend, Tungsten and Bismuth are metals which are poor conductors of electricity. Stainless Steel is a poor conductor because it has an alloy structure.
Metals That Conduct Heat the Best
Silver. Silver is one of the best metals for conducting heat because it works as a powerful reflector. Copper. Copper is yet another good conductor of heat because it absorbs heat quickly and holds it for a long period of time. Aluminum. Brass.
Which is the best conductor of heat and electricity?
Among the best conductors of heat and electricity is silver. Silver Metal with a thermal conduction value of approximately 430 w/(mk). gold and copper both come near to silver respectively, and with copper being considerably less expensive in many applications it is often preferred over the silver.
What is the most conductive material on earth?
As a result, silver is by far the most conductive metal on Earth. This is because silver only has one valence electron. In addition, this single electron is free to move around with little resistance. As a result, metals like silver and copper are a few of the metals with this particular characteristic.
Is lead solder a good conductor?
Soldering is especially useful for electronics because not only does it create a strong physical connection between metals, but it also creates an excellent conductive path for electric current to flow from one conductor to another. This is because the solder itself is an excellent conductor.
The heat is transferred directly from one particle to another due to vibrations in the process of conduction. Thus, mercury and lead are comparatively poor conductors of heat.
Which material is a better conductor?
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 wide use of pure silver has a couple of drawbacks.
Which among the following is a better conductor?
Answer Expert Verified
of course, silver is the best conductor of electricity. as you know, a conductor of electricity means current flows through it. or you can say that value of resistivity is lower. that’s why silver is the best conductor of electricity.
