conductors, insulators, and simple circuits

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 an insulator?

Back

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

Front

Give an example of a conductor.

Back

A penny is an example of a conductor.

Front

Give an example of an insulator.

Back

A plastic ruler is an example of an insulator.

Front

What happens in a simple circuit?

Back

In a simple circuit, electricity flows from a power source, through a conductor, and back to the power source, allowing devices to work.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit. It can open (stop) or close (allow) the circuit.

Front

What materials can be used to make a simple circuit?

Back

Materials include a power source (like a battery), wires (conductors), and a device (like a light bulb) that uses electricity.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, all components are connected in a single path. In a parallel circuit, components are connected across multiple paths.

Front

Why are metals good conductors?

Back

Metals have free electrons that can move easily, allowing electricity to flow.

Front

What is an example of a material that is both a conductor and an insulator?

Back

Graphite is a material that can conduct electricity but is not as efficient as metals.
