Answer 2

An electric fuse is an electrical safety device that is used for the purpose of preventing a short circuit. It is installed in electrical circuits or devices to prevent the device from damage due to excessive flow of current. The fuse consists of a wire with Low melting point, which when subjected to a magnitude of current higher than the current rating of the device, melts to open the circuit, thereby preventing the flow of excess current through the device.
