Electricity

Front

What is electrical energy primarily converted into when using a lamp?

Back

Light energy.

Front

What happens to current flow in a circuit when a good insulator is tested?

Back

No current flows through the circuit.

Front

What could NOT cause a light bulb to not light up in a circuit?

Back

A closed circuit.

Front

Why is copper considered a good conductor of electricity?

Back

Because it allows electric current to flow easily.

Front

What is a characteristic of metals that makes them good conductors of electricity?

Back

They have free electrons that can move easily.

Front

What does an open switch in a circuit do?

Back

It breaks the circuit, preventing current from flowing.

Front

What is the role of a circuit in electrical systems?

Back

To provide a path for electric current to flow.

Front

What is the difference between a conductor and an insulator?

Back

Conductors allow electric current to flow, while insulators do not.

Front

What material is commonly used as an insulator in electrical wiring?

Back

Rubber or plastic.

Front

What is the purpose of a light bulb in a circuit?

Back

To convert electrical energy into light energy.
