Q8. Which of the following is related with fuse wire?
A. Low resistance and low melting point
B. High resistance and low melting point
C. Low resistance and high melting point
D. High resistance and high melting point
A. Low resistance and low melting point
The fuse wire 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.
