Science 5.6B

Front

What is a complete circuit?

Back

A complete circuit is a closed loop that allows electricity to flow from the power source, through the components (like light bulbs), and back to the power source.

Front

What happens if a circuit is incomplete?

Back

If a circuit is incomplete, electricity cannot flow, and devices like light bulbs will not work.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to power the circuit.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily, helping to protect and contain the electrical current.

Front

What is a switch in an electrical circuit?

Back

A switch is a device that can open or close a circuit, allowing or stopping the flow of electricity.

Front

What happens to bulbs in a series circuit if one bulb goes out?

Back

In a series circuit, if one bulb goes out, all bulbs will go out because the circuit is broken.

Front

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

Back

In a series circuit, components are connected one after another, while in a parallel circuit, components are connected across the same voltage source.

Front

What is the function of wires in a circuit?

Back

Wires conduct electricity from one component to another, connecting the power source to the devices.

Front

What does it mean for a circuit to be 'closed'?

Back

A closed circuit means that there is a complete path for electricity to flow, allowing devices to operate.

Front

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

Back

A light bulb converts electrical energy into light energy, allowing us to see.
