Insulators

Front

What is the term for materials that allow heat and electricity to flow through them easily?

Back

Conductors

Front

Give an example of a common insulator used in electrical wiring.

Rubber

Front

What is the primary characteristic of a conductor?

Back

Conductors have free electrons that allow the flow of electric current.

Front

Name a common conductor used in electrical circuits.

Back

Copper

Front

What is the role of insulators in electrical systems?

Back

Insulators prevent the unwanted flow of electricity and protect users from electric shock.

Front

What happens to the resistance of a conductor as its temperature increases?

Back

The resistance typically increases as temperature increases.

Front

What is the difference between a conductor and an insulator in terms of electron movement?

Back

Conductors have free electrons that move easily, while insulators have tightly bound electrons that do not move freely.

Front

What is a semiconductor?

Back

A material that has conductivity between that of an insulator and a conductor, often used in electronic devices.

Front

How do insulators affect the efficiency of electrical systems?

Back

Insulators improve efficiency by reducing energy loss due to leakage currents.
