5.4.2 Open and Closed Circuits

Front

What is an open circuit?

Back

An open circuit is a circuit that is not complete, meaning that electricity cannot flow through it.

Front

What is a closed circuit?

Back

A closed circuit is a complete circuit that allows electricity to flow through it.

Front

What happens to a light bulb in an open circuit?

Back

The light bulb will not light up because the circuit is not complete.

Front

What is current?

Back

Current is the flow of electrons through a circuit.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where there are multiple paths for electricity to flow.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where all components are connected in a single path.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity by opening or closing the circuit.

Front

What does it mean when a circuit is short-circuited?

Back

A short circuit occurs when electricity takes an unintended path, often causing excessive current flow.

Front

Can a circuit work with a burned-out bulb?

Back

No, if a bulb is burned out, it breaks the circuit and prevents electricity from flowing.

Front

What is the difference between a closed circuit and an open circuit?

Back

A closed circuit allows electricity to flow, while an open circuit does not.
