Insulators and Conductors

Front

What is the definition of a conductor?

Back

A conductor is a material that allows the flow of electric current or heat through it easily.

Front

What is the role of a battery in an electrical circuit?

Back

A battery provides the energy needed to drive the current through the circuit.

Front

Is aluminum foil a conductor or an insulator?

Back

Aluminum foil is a conductor.

Front

What is the primary characteristic that distinguishes conductors from insulators?

Back

Conductors have free electrons that allow electricity to flow, while insulators have tightly bound electrons.

Front

What happens to the flow of electricity in an insulator?

Back

The flow of electricity is restricted or blocked in an insulator.

Front

Which material is often used as an insulator in electrical applications?

Back

Plastic is often used as an insulator in electrical applications.

Front

What is the significance of using insulators in electrical circuits?

Back

Insulators prevent unwanted flow of electricity, protecting users and ensuring the circuit functions properly.
