Circuits 5.8B

Front

What is a circuit?

Back

A circuit is a closed path through which electric current flows.

Front

What happens when a switch is closed in a circuit?

Back

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

Front

What happens when a switch is open in a circuit?

Back

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

Front

What is the role of a lightbulb in a circuit?

Back

A lightbulb converts electrical energy into light energy when electricity flows through it.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where there are multiple paths for electricity to flow, so if one path is broken, others can still work.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where all components are connected in a single path, so if one component fails, the entire circuit stops working.

Front

What is the function of a battery in a circuit?

Back

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

Front

What is a buzzer in a circuit?

Back

A buzzer is a device that produces sound when electricity flows through it.

Front

What is the effect of adding more lightbulbs in a series circuit?

Back

Adding more lightbulbs in a series circuit can make each bulb dimmer because the total voltage is shared among all bulbs.

Front

What is the effect of adding more lightbulbs in a parallel circuit?

Back

Adding more lightbulbs in a parallel circuit does not affect the brightness of the other bulbs; each bulb receives the full voltage.
