What occurs to the current in a series circuit if a component fails?

In a series circuit, all components are connected in a single pathway for current flow. This means that the current must pass through each component in turn. If one component fails, it creates an open circuit, breaking the continuous path for current. As a result, current cannot flow through the circuit at all. Therefore, the current stops completely when a component fails. This principle highlights the dependency of current flow on each component being functional within a series circuit, emphasizing the importance of each component in maintaining the circuit's operation.
