A) Light melting point
B) High ductility
C) High resistivity
D) low melting point
Correct Answer: D
Solution :
[d] The fuse element is made of zinc, copper, silver, aluminum, or alloys to provide stable and predictable characteristics. Fuse should be of low resistance and low melting point as per the requirement current rating for overcurrent protection. If excess charge flows through the fuse, it will melt and trips the circuit. Resistance should not be high (which will block current) or low (allow overcurrent).
