Question : Which of the following statements is correct regarding fuse wire?
Option 1: It has a low melting point and low conductivity.
Option 2: It has a high melting point and low conductivity.
Option 3: It has a low melting point and high conductivity.
Option 4: It has a high melting point and high conductivity.
Correct Answer: It has a low melting point and high conductivity.
Solution : The correct answer is that it has a low melting point and high conductivity .
The material used to make fuse wire has a high conductivity and a low melting point. It will prevent excessive power from flowing through it if it is placed into an electric circuit. The fuse wire heats up, melts and breaks the circuit when the current reaches its limit. It is composed of a lead (Pb) and tin (Sn) alloy.
