Final answer:
A closed circuit is characterized by charges not flowing. If the circuit is open or broken, devices connected to the circuit will not work.
Step-by-step explanation:
One feature of a closed circuit is that charges do not flow. In a closed circuit, the flow of charges is continuous and uninterrupted, allowing electrical devices to function properly. If the circuit is open or broken, the flow of charges will be interrupted and the devices connected to the circuit will not work.
