What happens to the electron flow when connected to a closed circuit?

When a circuit is closed, it provides a complete path for the electrons to flow. In this state, the electrons are able to move continuously around the circuit, driven by a potential difference (voltage) provided by a power source, such as a battery or generator. This movement of electrons constitutes an electric current.

In a closed circuit, the flow of electrons occurs in a loop, allowing the circuit components, like resistors, capacitors, and lights, to operate as designed. If the circuit were to become open or interrupted, then the flow would cease altogether, which is why the choice indicating that electron flow continues in a loop is the correct understanding of the behavior in a closed circuit. This continuous flow is essential for powering devices and enabling various electrical systems to function properly.
