Circuits

Front

What is a circuit?

Back

A circuit is a closed path through which electricity flows.

Front

What is a complete circuit?

Back

A complete circuit is one where the path is unbroken, allowing electricity to flow and power devices like light bulbs.

Front

What happens when a switch is closed?

Back

When a switch is closed, it completes the circuit, allowing electricity to flow and turn on devices.

Front

What happens when a switch is open?

Back

When a switch is open, it breaks the circuit, stopping the flow of electricity and turning off devices.

Front

What materials are needed to create a complete circuit?

Back

You need a power source (like a battery), conductive materials (like copper wire), and a device to use the electricity (like a light bulb).

Front

What is an insulator?

Back

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

Front

What is a conductor?

Back

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

Front

Why might a light bulb not turn on?

Back

A light bulb may not turn on if it is not part of a complete circuit, if the battery is dead, or if the bulb is broken.

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 does it mean for a circuit to be 'broken'?

Back

A broken circuit means there is a gap in the path, preventing electricity from flowing.
