Fuses

A fuse is a safety device in electrical systems that prevents damage caused by excess current. It contains a thin metal strip that melts and breaks the circuit if too much current flows through, stopping potential damage or fires. Once blown, the fuse must be replaced before the circuit can function again. Fuses are essential for protecting appliances, wiring, and users from electrical faults by acting as a sacrificial component that sacrifices itself to maintain overall safety.
