Pure substances such as rubber, glass, and plastic are among the worst electrical conductors because they have high resistance to the flow of electric current. These materials are often used as electrical insulators to prevent or limit the flow of electricity.

Tell the best and worst conductor of electricity?

Silver is one of the best conductors of electricity due to its high electrical conductivity. In contrast, rubber is one of the worst conductors of electricity because it is an insulator and does not allow electrical current to flow easily.


What is an electrical insulator an conductor?

An electrical insulator is a material that does not conduct electricity, meaning it prevents the flow of electrical current. Examples include rubber, glass, and plastic. In contrast, an electrical conductor is a material that allows the flow of electrical current, such as metals like copper and aluminum.


What type of substances would be a good electrical conductor?

Metals such as copper, silver, and gold are good electrical conductors due to their ability to easily allow the flow of electric charge. Graphite, a form of carbon, is also a good conductor. In general, materials with high electrical conductivity and free-moving electrons are good electrical conductors.


Is a pencil an insulator or conductor of electricity?

Note: "electricity" is not conducted, only electrical current (the flow of electrons) is. Electricity is the field that covers all things electrical. The wood in a pencil is an insulator. If it is wet, it is a poorer insulator, but only a poor conductor. The carbon (lead) in the pencil is a poor conductor. The metal holding the eraser is a good conductor. The rubber eraser is a poor conductor. You really have to address the conductivity of specific substances, not items that are build from a variety of substances.


What is the purpose of a conductor shield in electrical cables?

The purpose of a conductor shield in electrical cables is to protect the conductor from electromagnetic interference and to prevent leakage of electrical signals.

Is rubber a conductor of electrical circuits?

Virtually every substance is a conductor of electrical current to a greater or lesser degree. We use the best ones to build extension cords and to connect electronic components to one another, and we use the worst ones as 'insulators'. Rubber is one of the worst ones.

What Substances would be a good electrical conductor C(s) kCl(s) Al(s)?

Aluminum (Al) would be a good electrical conductor due to its high conductivity. Carbon (C) in the form of graphite can also conduct electricity well. However, potassium chloride (KCl) in solid form is not a good conductor of electricity.
