Types of Electrical Conductors

Iron has metallic bonds which is where the electrons are free to move around more than one atom. This is called delocalization. Because of this, iron is a good conductor.

In order to conduct electricity, a substance needs to have charges that are free-moving. Electrons are negatively-charged subatomic particles of an atom. Metals, such as iron, have metallic bonds. Because the electrons involved in the metallic bond of iron are free-moving, iron is a good conductor.

Metals conduct electricity by allowing free electrons to move between the atoms. These electrons are not associated with a single atom or covalent bond. Some materials, including copper, will readily conduct both heat and electricity. While others, like glass, conduct heat but not electricity.

Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air.

• Hard Drawn Copper Conductor.
• Cadmium Copper Conductor.
• Steel-Cored Copper Conductor (SCC)
• Copper Welded Conductor.
• Hard-Drawn Aluminium Conductor or All-Aluminum Conductor.
• Aluminium Conductor Steel Reinforced.
• Smooth Body ACSR Conductor.
• Expanded ACSR Conductor.

Materials that are poor conductors of electricity are called insulators. Some examples are wood, glass, plastics, non-metal elements that are polymers of hydrocarbons. So among the following options aluminum, silver and copper are metals and these are good conductors of electricity.

Along with its carbon cousins graphite and graphene, diamond is the best thermal conductor around room temperature, having thermal conductivity of more than 2,000 watts per meter per Kelvin, which is five times higher than the best metals such as copper.

Heat is conducted both by electrons and by lattice vibrations (phonons). Diamond has a very rigid lattice which is quite conducive to effective phonon conduction. Due to this strong covalent bond electrons are localised, hence there are no free electrons available. Thus diamond is bad conductor of electricity.

Diamond is a form of carbon in which each carbon atom is joined to four other carbon atoms, forming a giant covalent structure. As a result, diamond is very hard and has a high melting point. It does not conduct electricity as there are no delocalised electrons in the structure.

Thermal conductivity Unlike most electrical insulators, diamond is a good conductor of heat because of the strong covalent bonding and low phonon scattering. Diamond’s high thermal conductivity is used by jewelers and gemologists who may employ an electronic thermal probe to distinguish diamonds from their imitations.

Diamond is insoluble in water. It does not conduct electricity. Every atom in a diamond is bonded to its neighbours by four strong covalent bonds, leaving no free electrons and no ions .

Are Diamonds Stronger than Steel? Steel is also denser than diamonds because each molecule weighs much more than a carbon atom alone. A diamond’s smoothness allows it to easier to resist wear and tear for tools such as diamond tipped drills.

Oil is an insulator and is a bad conductor of electricity.

Explanation: Vegateble ghee is an example of fats. Oils and fats are good conductors of heat and electricity. Explanation: Oils and fats are poor conductors of heat and electricity. They do not allow heat or electricity to pass through them.

no all liquid doesn’t conduct electricity eg: water is a liquid and it doesn’t conduct electricity. Yes to conduct electricity solution must release free ions or charged electrons or their respective atoms to conduct electricity.

Tap water, lemon juice and mercury is the best liquid conductor compare with others. Because of any solution to conduct, you need ions or free electrons. So these are good conductor having contain free ions.

Milk is a good conductor of electricity because it contains water and lactic acids and other salts. Honey is a solution of sugars. So, it does not conduct because it does not have ions or charged particles.

The answer is in our sweat. Unlike the epidermis and dermis layers of our skin — which are poor conductors of electricity — our sweat is rich with electrolytes such as sodium and chloride, which makes our sweat a surprisingly decent conductor of electricity (though not quite as good as metal).
