Which of the following is an essential physical property of the wires uses for making fuses?

A. Low density
B. Hypothermal conductivity
C. Low electrical resistivity
D. Low melting point

Correct Answer:

Option D – Low melting point

Explanation

Fuse wires have a low melting point so that if a huge amount of current is passed through it to any appliance than that wire would melt and stop the appliance from getting damaged by not letting the current pass any further.
