✌ AN EXPERIMENTAL SET UP ✌

We can easily illustrate the action of an electric fuse.

*⃣ TO DO :- Carefully observe any switchboard.

*⃣ IMPORTANT REQUIREMENTS :- Circuit (Closed circuit), Electric fuse which is properly tested.

*⃣ GENERAL OBSERVATION : We can observe that the fuse consists of a piece of thin wire (generally an alloy of tin and lead) having low melting point but high resistivity.

*⃣ ACTION (MECHANISM) : When an excessive current will flow in that household circuit, then thin fuse wire will get heated too much, and hence it will melt and breaks the circuit immediately.

*⃣ USEFUL POINT : Due to this action, the current stops flowing in that circuit and thus, damage to various electrical appliances is prevented.
