Question
Fuse wire is made up of alloys of
- High boiling point
- High melting point
- Low melting point
- Low boiling point
Hint:
Low melting point
The correct answer is: Low melting point
Because of its strong resistance and low melting point fuse wire is formed of tin and lead alloy.
Material to be used in fuse wire must have low melting point, low boiling point and high electric resistance so that it will melt easily.
