What happens in a series circuit if one component fails?

In a series circuit, all components are connected along a single path for the electrical current to flow. If one component in this series circuit fails or becomes disconnected, it breaks the continuity of the circuit. As a result, the entire circuit is interrupted, which means that current cannot flow through the circuit any longer. This behavior is a fundamental characteristic of series circuits; they rely on every component functioning properly to maintain the flow of electricity.

For example, if you consider a string of lights connected in series, if one bulb burns out or is removed, the whole string will go dark because the circuit is incomplete. This illustrates the principle that the failure of one component results in the failure of the entire circuit.
