Safety fuse wire used in domestic electrical appliances is made of metal of low
-
Resistance
-
Melting point
-
Specific gravity
-
None of above
B
Correct answer
Explanation
Safety fuse wires must melt quickly when excessive current flows to break the circuit and prevent damage. A metal with low melting point ensures the fuse blows at the designed current rating, protecting appliances from overheating or fire. High resistance would cause voltage drop without necessarily melting.
