How are electrical appliances used to protect us?

Electrical appliances are designed with safety features that help protect us from hazards such as electrical shocks, fires, and overheating. For example, circuit breakers and fuses prevent overloads by cutting off electricity flow when too much current is detected. Additionally, appliances like smoke detectors and carbon monoxide alarms alert us to dangerous situations, while safety switches can automatically disconnect power in emergencies. Overall, these devices enhance our safety by minimizing risks associated with electricity and its usage.
