What happens to a parallel circuit when one device fails?

In a parallel circuit, each device is connected independently to the power source. This setup allows current to flow through multiple paths. When one device in a parallel circuit fails, such as a light bulb burning out or an appliance malfunctioning, that specific device is affected while the rest of the devices continue to operate normally. This behavior is one of the key advantages of parallel circuits, as it ensures that the failure of one component does not disrupt the entire system. The unaffected components maintain their operation and power supply, highlighting the reliability of parallel arrangements in electrical systems. The other options do not accurately represent this characteristic of parallel circuits.
