Which is the best conductor? Silver or gold? Why? Gold has superior stability in terms of electrical or thermal conduction at low to high temperature range and harsh environmental conditions. Silver losses its characteristics when temperature varies from 20 to 100 degree centigrade. This is why, gold is best conducting material in practical and silver is highest conducting material at ideal.

Electrical conductor Electrical conductor. In physics and electrical engineering, a conductor is an object or type of material that allows the flow of an electrical current in one or more directions. Materials made of metal are common electrical conductors. Electrical current is generated by the flow of negatively charged electrons, positively charged holes, and positive or negative ions in some cases. In order for current to flow, it is not necessary for one charged particle to travel from the machine producing the current to that consu

What Materials Are Good Conductors of Heat? A: Many metals, like silver, copper, gold and aluminum, are good thermal conductors. Thermal conductors are materials that heat passes through easily. Conduction, or the transfer of heat, can take place within a single material or between two objects.

Which Metals Conduct Electricity? You may be surprised to learn that copper is not even the most conductive metal despite being used in many common applications (and the fact it is used as the measuring stick for rating conductivity in metals). Another common misconception is the pure Gold is the best conductor of electricity. While Gold does have a relatively high conductive rating, it is actually less conductive than Copper. Which metal conducts electricity the best? The answer: Pure Silver. The problem with Silver is that it can tarnish.

- Other materials that are sometimes used as conductors are silver, gold, and aluminum. Copper is still the most popular material used for wires because it is a very good conductor of electrical current and it is fairly inexpensive when compared to gold and silver.

Why is copper such a good conductor, although it has only one free electron? Atoms of some elements let go of their outer electrons pretty easily, which makes these elements good conductors. In other elements, the atoms hold on to their electrons, so these elements don't conduct electricity as well. Copper and silicon are used here as examples. The same general ideas apply to other elements. ...

Example of good conductor of electricity? Best Answer: Any material that conducts heat or electricity (as opposed to an insulator, or nonconductor). A good conductor has a high electrical or heat conductivity, and is generally a substance rich in loosely-held free electrons, such as a metal.Copper and aluminum are good conductors.A poor conductor (such as the non-metals glass, porcelain, and rubber) has few free electrons and resists the flow of electricity or heat. Carbon is exceptional in being non-metallic and yet (in some of its forms) a relatively good conductor of heat and electricity.est Answer: Any material that conducts heat or electricity (as opposed to an insulator, or nonconductor). A good conductor has a high electrical or heat conductivity, and is generally a substance rich in loosely-held free electrons, such as a metal.

- The opposite is not true. There are lot of good non-metallic conductors. Semiconductors may be very good conductors, there are conducting polymers (not as good as copper or aluminum but properly produced they should conduct better than some metals), graphene is a good conductor.

- Copper is a better conductor because what really conducts electricity in water are the particles that contaminate it like metals and salts. Pure water (water that is free from contaminants like salts) is actually the world's best insulator.

Is copper a good conductor of electricity? The best conductors are silver, copper, gold and aluminum respectively. Cost, weight and ease of handling dictate using copper or aluminum as conductors in most industries. Also it is used in piping as it is unreactive with water.

Types of Government: Autocracy, Democracy & Oligarchy The advantages of an autocratic government are that decisions can be made and implemented quickly. However, individual rights are usually ignored and power is often maintained by force. Some autocracies are theocratic governments, in which the ruler claims to have been put in power by a deity.

Good and bad conductors of heat Good and bad conductors of heat. Most metals are good conductors of heat; silver and copper are exceptionally good. On the other hand, substances such as cork, wood, cotton and wool are bad conductors. Both good and bad conductors have their uses. The “bit” of a soldering iron is made of copper, so that when its tip is cooled through contact with the work, heat is rapidly conducted from the body of the bit to restore the temperature of the tip and maintain it above the melting-point of solder.

Conductors and Insulators Most atoms hold on to their electrons tightly and are insulators. In copper, the valence electrons are essentially free and strongly repel each other. Any external influence which moves one of them will cause a repulsion of other electrons which propagates, domino fashion through the conductor. Simply stated, most metals are good electrical conductors, most nonmetals are not.

Conductors Examples A conductor is any piece of material that easily allows heat or electricity to pass through it. Many different materials can be conductors but metals are the best conducting materials that are available to us. A conductor allows electrons to flow freely across its surface.

What conducts electricity? We know that in, general, metals and superconductors, as well as plasmas and ionic solutions conduct electricity. Of the metals, silver conducts electricity the best, although it is relatively expensive. Copper is very commonly used because it is the second most conductive metal. We know that Group 1 and Group 2 metals (the alkali and alkaline earth metals) from the periodic table are good conductors.

- Electricity flows through objects that are conductors and doesn’t flow through objects that are insulators. Good conductors are generally made of metal such as copper, aluminum, silver, gold, brass, tin, and lead. Good insulators are often made of glass, plastic, rubber, ceramic, or cloth.

- Metals make good conductors because the outer electrons of their atoms are loosely attached, and the electrons can drift through the metal when a voltage is applied. Some materials have all their electrons firmly fixed in place, so they do not conduct electricity well.A material like this is called an INSULATOR. conductor is a material that allows electric charge to move through it as an electric current. Usually the charge is carried by electrons, and the conductor is a metal.

What are good conductors of heat? As a rule, a good conductor of electricity is also a good conductor of heat. So you have a long list of metals.Among nonmetals, mica is very good conductor of heat, though it is very poor conductor for electricity. Among the best conductors, you have silver, gold, copper and Aluminium.
