Electrical Energy Review

Front

What is an insulator?

Back

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

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 a closed circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow. It has no breaks or gaps.

Front

What is an open circuit?

Back

An open circuit is a broken electrical loop that prevents current from flowing. It has a gap or break.

Front

What materials can complete a circuit?

Back

Materials that can complete a circuit include conductors like metal wires and nails.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor.

Front

What happens when you touch a conductor?

Back

When you touch a conductor, you can feel the electrical energy if the circuit is complete and the current is flowing.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit by opening (turning off) or closing (turning on) the circuit.

Front

What is a battery?

Back

A battery is a device that stores electrical energy and provides power to a circuit.

Front

What is a circuit diagram?

Back

A circuit diagram is a visual representation of an electrical circuit, showing how components are connected.
