4th Science Electricity, Conductors, and Insulators

Front

What is a circuit?

Back

A circuit is a complete path through which electricity can flow, allowing devices like lights or trains to operate.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily, such as rubber or plastic.

Front

What is electricity?

Back

Electricity is the flow of charged particles, usually electrons, through a conductor.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as metals like copper and aluminum.

Front

What happens when a circuit is complete?

Back

When a circuit is complete, electricity can flow through it, powering devices like light bulbs.

Front

Give an example of a good conductor.

Back

Copper is a good conductor of electricity.

Front

Give an example of a good insulator.

Back

Rubber is a good insulator that prevents electricity from flowing.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to push the current through the circuit.

Front

What is the purpose of wires in a circuit?

Back

Wires connect different components in a circuit and allow electricity to flow between them.

Front

What happens if a circuit is broken?

Back

If a circuit is broken, electricity cannot flow, and devices connected to the circuit will not work.
