Front

What is the primary function of a radio in terms of energy conversion?

Back

A radio converts electrical energy into sound energy.

Front

Identify an example of energy conversion that does NOT involve electricity.

Back

A windmill is NOT an example of electricity converting into another form of energy.

Front

What type of energy does a lamp convert electrical energy into when turned on?

Back

A lamp converts electrical energy into light.

Front

What components of a circuit are activated when the switch is closed?

Back

The buzzer, electric motor, and light bulb will turn on when the switch is closed.

Front

What happens to the light bulb when a switch in an electric circuit is opened?

Back

Back

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

Front

What is energy conversion?

Back

Energy conversion is the process of changing energy from one form to another.

Front

What is the role of a switch in an electric circuit?

Back

A switch controls the flow of electricity in a circuit, allowing it to be turned on or off.

Front

Explain the difference between an open circuit and a closed circuit.

Back

An open circuit has a break that prevents current from flowing, while a closed circuit allows current to flow continuously.

Front

What is a buzzer and how does it work in an electric circuit?

Back

A buzzer is a device that produces sound when electrical energy passes through it.
