Exploring Electricity and Circuits

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily. Examples include plastic and glass.

Front

What is required for the flow of electricity?

Back

A complete path is required for electricity to flow.

Front

What is the difference between a closed circuit and an open circuit?

Back

A closed circuit allows electricity to flow, while an open circuit does not.

Front

Why are metals considered good conductors of electricity?

Back

Metals are considered good conductors because they have free electrons that allow electricity to flow easily.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily. Examples include metals like copper and aluminum.

Front

What is the role of a circuit in electricity?

Back

A circuit provides a complete path for electricity to flow from a power source to a load and back.

Front

What is the function of a switch in a circuit?

Back

A switch is used to open or close a circuit, controlling the flow of electricity.

Front

What materials are typically used as insulators?

Back

Common insulators include rubber, glass, plastic, and wood.

Front

What happens to electricity in an open circuit?

Back

In an open circuit, the flow of electricity is interrupted, preventing current from reaching the load.

Front

What is the significance of free electrons in conductors?

Back

Free electrons in conductors allow for the easy flow of electric current, making them effective for conducting electricity.
