What happens to current flow when a circuit is closed?

When a circuit is closed, it creates a complete path for the current to flow. In this state, electrons are able to move freely through the conductive materials, allowing the current to travel continuously throughout the circuit. This flow is maintained as long as the circuit remains closed and there are no breaks or gaps in the conductive loop.

A closed circuit is essential for the operation of electrical devices. When the circuit is open, current cannot flow, and the devices connected to the circuit will not function. The correct understanding of a closed circuit is that it permits uninterrupted current flow, which is essential for the operation of electrical systems and devices.

The other choices imply changes that do not typically occur in a closed circuit. For instance, the assertion that current ceases in a closed circuit contradicts the fundamental principles of electricity, as current flow is the defining characteristic of a closed circuit. Similarly, ideas about the current increasing or remaining constant may apply under different circumstances but do not describe the fundamental feature of a closed circuit as well as the notion of continuous flow does.
