What happens to current in a series circuit when one component fails?

In a series circuit, all components are connected in a single path for the electrical current to flow. This means that the same amount of current flows through each component one after another. When one component fails, it typically creates an open circuit, interrupting this continuous path. As a result, the current cannot flow past the failed component, causing the entire circuit to cease operation.

This characteristic of series circuits is crucial to understand; the current will stop flowing entirely, impacting all devices or components downstream from the failure point. Therefore, selecting the option that states the current stops flowing entirely accurately reflects what occurs in a series circuit when one component fails.
