Describe an experiment to illustrate the action of an electric fuse.

Take a thin fuse wire made of tin or tin-alloy having low melting point. Place this fuse wire on the porcelain fuse grip and insert the grip into the fuse holder. Now switch on all the electrical appliances of high power rating like electric iron, water heater, air conditioner, etc., . Since the melting point of the fuse wire is much lower, it melts and breaks the circuit.
