What happens when components in a parallel circuit fail?

In a parallel circuit, multiple components are connected across the same voltage source, allowing each component to operate independently of the others. When one component fails, it typically breaks the current path only for that specific component, meaning the remaining components will continue to function normally. This independence is a key characteristic of parallel circuits, which provides a level of redundancy and reliability.

Therefore, if one component were to fail, only that particular component is affected, while the rest remain operational, continuing to receive the full voltage supply. This allows the circuit as a whole to still perform its intended function, demonstrating the advantages of parallel connections in electrical systems.
