Superconductors are materials that offer no electrical resistance whatsoever but the highest temperature any known superconductor can be while retaining its conductive properties is -181 degrees Celsius, making them an extremely impractical and expensive material for most purposes. As far as I know the most conductive material at room temperature is pure silver, which is slightly more conductive then pure copper and 50% more conductive then pure gold. Copper and gold are both used commonly for conduction however because copper is much cheaper then silver and nearly as conductive, and gold is more resistant to corrosion then either silver or copper despite its reduced capacity for electrical conduction.
What else can I help you with?
What material make good conductors?
Good conductors of electricity are materials that allow electric current to flow easily through them. Metals such as copper, silver, and gold are excellent conductors due to their high electron mobility and low electrical resistance. Other materials like aluminum and iron are also decent conductors but not as efficient as pure metals.
What two properties of metal make them useful materials for the electrical wiring at home?
Metals have high electrical conductivity, allowing electricity to flow easily through them. They also have good ductility, meaning they can be easily shaped into wires without breaking, making them ideal for conducting electricity in homes.
What are elements that are usually good conductors of heat and electricity and are also typically malleable and ductile?
Metals such as copper, silver, gold, and aluminum are typically good conductors of heat and electricity while being malleable and ductile. These properties make them ideal for use in electrical wiring, circuits, and various industrial applications where thermal and electrical conductivity are important.
What makes something a good conductor of heat?
Good conductors of heat have closely-packed atoms with free electrons that can move easily through the material, transferring heat energy rapidly. Additionally, materials with high thermal conductivity, such as metals like copper and aluminum, are typically good conductors of heat. Smooth surfaces without gaps or voids also enhance the efficiency of heat conduction.
Why does objects conduct electricity?
All materials have some amount of electrical resistance.The flow of electron is resisted by the collision of electron with neighbouring atom.So the free flow of electron is not obtained and hence conductor offer resistance.Although this is very small as ccompared to insulator and semiconductor but it exist
What material make good conductors?

Metals such as copper, silver, and gold are excellent conductors due to their high electron mobility and low electrical resistance. Other materials like aluminum and iron are also decent conductors but not as efficient as pure metals.
What are three materials that make good conductors?
Copper, silver, and gold are three materials that make good conductors of electricity due to their low resistance and high conductivity properties.
Name two other materials that are poor conductors of electricity and might make good insulators?
Two other materials that are poor conductors of electricity and good insulators are rubber and glass. Rubber is commonly used in electrical cords and cables due to its insulating properties, while glass is a common insulator in electronics and construction materials.

What materials make the best conductors?
Metals like copper, gold, and silver are known to be excellent conductors of electricity due to their high conductivity levels. These materials have free electrons that can move easily through the material, allowing for the efficient flow of electrical current.
Why is it useful to know which materials are electrical conductors?
it is useful to know which materials are electrical conductors so if you wanted to make an electric current you could. For example is you where making a circuit you would need to know which materials you could use that would conduct electricity.or if there is something stuck in a power point you know what material to use to get it out without getting electrocuted
Make a list of materials which are good conductors of heat and materials which are good insulators of heat from objects at home?
Generally, things that feel cold to touch (in a normal temperature room and no heating applied to them) are good conductors of heat (metals for example). Poor conductors tend to feel neither hot or cold under normal conditions (wood for example).
Which makes a good insulator?
Materials with high resistance to the flow of electricity make good insulators. Examples include rubber, plastic, glass, and ceramic. These materials are poor conductors and are used to prevent the flow of electricity in electrical systems.
What are things that make use of conductors and insulators?
Conductors, such as metals, are used in electrical wiring to conduct electricity efficiently. Insulators, such as rubber and plastic, are used to coat electrical wires to prevent electric shock and short circuits. Insulators are also used for building materials to maintain temperature and prevent heat transfer.
What are elements that are usually good conductors of heat and electricity and are also typically malleable and ductile?

These properties make them ideal for use in electrical wiring, circuits, and various industrial applications where thermal and electrical conductivity are important.
Is it necessary to measure the conductivity of a material?
In many cases, yes, it is necessary to measure the conductivity of a material. We need to know how well materials conduct electricity, particularly if these materials are used in the construction of anything electrical or electronic. We need to know what we can use around electrical circuits that won't conduct well, and we need to find things to make up that circuit that are good conductors. Simple, easy to understand.
Are all objects considered conductors?
Assuming you mean an electrical conductor, No. To be a conductor, a material must have free electrons in the conduction band of the atoms. Metals have free electrons intrinsically in these bands, and so make great conductors. If you mean heat conductors, the answer is also no. Some objects are insulators of heat.
