How does the failure of one light bulb affect the others in a parallel circuit used for lighting?

In a parallel circuit, each light bulb has its own independent path to the power source. This design means that the failure of one bulb does not interrupt the flow of electricity to the others. When one bulb fails, it creates an open circuit at that specific point, but the remaining bulbs continue to receive electrical power. Therefore, only the failed bulb goes out, while the others remain lit and function normally. This characteristic is one of the key advantages of parallel circuits, as it enhances reliability in lighting systems because the failure of one component does not result in a total loss of functionality for the entire circuit.
