Final answer:
When a circuit is closed, it means there is an uninterrupted path for electricity to flow.
Step-by-step explanation:
When we say that a circuit is closed, it means that there is an uninterrupted path for the flow of electricity. In a closed circuit, there are no breaks or gaps that would prevent the current from flowing. This allows the electricity to continuously travel around the circuit, powering the devices connected to it.
