Answer 1

Explanation:

                The most important safety, method used for protecting home appliances from short circuiting or overloading is the electric fuse. This is a safety device having thin wire of short length made of tin (25%) and lead (75%) alloy having low melting point around. The fuse wire is of chosen thickness, so as to fix its resistance and hence amount of heating on passage of a particular amount of current. Whenever current through the fuse exceeds the set limit, the fuse wire melts and breaks the circuit. This saves the main circuit components from damage.

Answer 2

Answer:

Melting on short circuit.

Explanation:

Fuse is made thin and from such an alloy that it melts on overheating on short circuit and hence prevents from damage.
