A switch is used to open or close a circuit, allowing or stopping the flow of electricity.

Front

What happens when a circuit is incomplete?

Back

When a circuit is incomplete, electricity cannot flow, and devices in the circuit 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 a series circuit?

Back

A series circuit is a type of circuit where components are connected one after another, so the same current flows through all components.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where components are connected across common points, allowing multiple paths for electricity to flow.
