What happens in a series circuit when one component fails?

In a series circuit, all components are connected in a single path, meaning that the current flows through each component sequentially. When one component fails, it creates an open circuit, interrupting the flow of electricity throughout that entire path. As a result, the entire circuit stops functioning. This is because the electric current cannot continue to flow past the point of failure, leaving all other components inactive. This behavior is a fundamental characteristic of series circuits, distinguishing them from parallel circuits, where a failure in one component does not affect the operation of the others. Understanding this principle is essential for diagnosing issues in series circuits and for systems design, where reliability and redundancy may need to be considered.
