WebFuses work on the principal of a large current melting the fuse wire. In some cases faults can occur in which the current may not be large enough to melt the fuse but enough to seriously harm the user of the electrical appliance. For protection against faults of this nature a circuit-breaker is used in place of a fuse. WebElectric Bell. When an electric current flows through a wire - especially one in the form of a coil - it becomes an electromagnet. It is a temporary magnet, as it can retain its newly …
