Conductor or Insulator

Front

What is a conductor?

Back

A conductor is a material that allows the flow of electric current or heat. Examples include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electric current or heat. Examples include rubber, glass, and wood.

Front

What are some common examples of conductors?

Back

Common examples of conductors include metals such as copper, aluminum, gold, and silver.

Front

What are some common examples of insulators?

Back

Common examples of insulators include rubber, glass, plastic, and dry wood.

Front

How does temperature affect the conductivity of materials?

Back

Generally, as temperature increases, the conductivity of conductors increases, while the conductivity of insulators decreases.

Front

What is the role of water in conductivity?

Back

Water can act as a conductor when it contains dissolved salts and minerals, which allow electric current to flow.

Front

What is the difference between a good conductor and a poor conductor?

Back

A good conductor has low resistance and allows electric current to flow easily, while a poor conductor has high resistance and restricts current flow.

Front

Can air be a conductor?

Back

Air is generally an insulator, but it can become a conductor under certain conditions, such as high voltage or ionization.

Front

What is the significance of conductivity in electrical applications?

Back

Conductivity is crucial in electrical applications as it determines how efficiently electricity can be transmitted through materials.

Front

What is the relationship between insulators and safety in electrical systems?

Back

Insulators are used in electrical systems to prevent accidental contact with live wires, ensuring safety by reducing the risk of electric shock.
