Which of the following describes what happens to current in a series circuit when one device is disconnected?

In a series circuit, all components are connected end-to-end, forming a single path for current to flow. When one device in this circuit is disconnected, it creates an open circuit, interrupting that single path. As a result, no current can flow through the circuit at all, meaning that the current stops completely. This behavior highlights a fundamental property of series circuits: because the devices are interconnected in a single pathway, the failure or disconnection of any one device prevents any of the current from being able to travel through the entire loop. Thus, current ceases to flow when a device is disconnected, which is why the correct answer is the cessation of current flow.
