Question: What Are The Top 5 Electrical Conductors?

What is a Class 1 conductor?

Conductors of different circuits.

Class 1 circuits can occupy the same cable, enclosure, or raceway without regard to whether the individual Class 1 circuits are AC or DC, provided all the Class 1 conductors are insulated for the maximum voltage of any conductor in the cable, enclosure, or raceway..

What is the best electrical conductor?

Silver also has the highest thermal conductivity of any element and the highest light reflectance. Although it is the best conductor, copper and gold are used more often in electrical applications because copper is less expensive and gold has a much higher corrosion resistance.

What are 3 types of conductors?

Conductors conduct electrical current very easily because of their free electrons.Insulators oppose electrical current and make poor conductors.Some common conductors are copper, aluminum, gold, and silver.Some common insulators are glass, air, plastic, rubber, and wood.

What are 3 examples of good conductors?

The most effective electrical conductors are:Silver.Gold.Copper.Aluminum.Mercury.Steel.Iron.Seawater.More items…•

Which metal is a poor conductor of electricity?

Bismuth and tungsten are two metals which are poor conductors of electricity. There are many, but some include Aluminum, Bismuth, Gallium, Indium, Lead, Thallium, Tin, Ununhexium, Ununpentium, Ununquadium, and Ununtrium.

What are 4 examples of insulators?

Examples of Conductors and Insulators Examples of conductors include metals, aqueous solutions of salts (i.e., ionic compounds dissolved in water), graphite, and the human body. Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air.

Which metal is best conductor of heat and electricity?

SilverSilver also has the highest thermal conductivity of any element and the highest light reflectance. Although it is the best conductor, copper and gold are used more often in electrical applications because copper is less expensive and gold has a much higher corrosion resistance.

Is Diamond a good conductor of electricity?

In diamond, all four outer electrons of each carbon atom are ‘localized’ between the atoms in covalent bonding. The movement of electrons is restricted and diamond does not conduct an electric current. Thus, graphite is a good conductor and diamond is not.

Who is the greatest conductor of all time?

Carlos KleiberCarlos Kleiber has today been crowned the greatest conductor of all time by a selection of 100 of today’s finest maestros….BBC Music Magazine’s 20 greatest conductors of all time are:Sir Colin Davis (b1927) British.Sir Thomas Beecham (1879-1961) British.Sir Charles Mackerras (1925-2010) Australian.More items…•

What are 10 examples of conductors?

10 Electrical ConductorsSilver.Gold.Copper.Aluminum.Mercury.Steel.Iron.Seawater.More items…•

Which metal is the best conductor of electricity?

SilverSilver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons). copper is used widely because of low cost than silver and gold.

Is plastic a good insulator?

Plastic Insulator Becomes a Heat Conductor. … Plastics are excellent insulators, meaning they efficiently trap heat—a quality that is an advantage in something such as a coffee cup sleeve.

What are 4 good conductors?

Conductors conduct electrical current very easily because of their free electrons.Insulators oppose electrical current and make poor conductors.Some common conductors are copper, aluminum, gold, and silver.Some common insulators are glass, air, plastic, rubber, and wood.

What is a good insulator?

A material that does not let heat and electricity travel through it easily is known as an insulator. … Plastic, rubber, wood, and ceramics are good insulators.
