A fuse is a device that works on the heating effect of electric current. It consists of a fuse wire which has low melting point. It is connected in series with the appliance in a circuit. Whenever there is high electric current, more heat will be produced and it leads to the melting of fuse wire. When fuse wire melts, the circuit is broken and in this way, it prevents damage to electrical appliances and avoids fire.
