In a series circuit, what happens if one component fails?

In a series circuit, all components are connected end-to-end, forming a single pathway for current to flow. When one component fails, it creates an open circuit, which interrupts the flow of electricity throughout the entire circuit. As a result, the current is unable to pass through the remaining components, causing all of them to stop functioning. This characteristic is fundamental to series circuits, as they depend on the complete continuity of the circuit for operation. Therefore, if any single component fails, the entire circuit will cease to operate, confirming that all components stop functioning when one component fails.
