Conductors and Insulators

Front

What is a conductor?

Back

A conductor is a material that allows the flow of electric current or heat. Metals like copper and aluminum are common conductors.

Front

Is water a conductor or an insulator?

Back

Pure water is a poor conductor, but impure water (like tap water) can conduct electricity due to dissolved minerals.

Front

What role do conductors play in electrical circuits?

Back

Conductors are used to connect different components of an electrical circuit, allowing current to flow.

Front

What role do insulators play in electrical circuits?

Back

Insulators are used to prevent the flow of electricity where it is not wanted, protecting users from electric shock.

Front

Why is the human body considered a conductor?

Back

The human body contains a significant amount of water and electrolytes, which allow it to conduct electricity.

Front

What is the significance of using insulators in electrical wiring?

Back

Insulators prevent accidental contact with live wires, reducing the risk of electric shock and short circuits.

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.
