Which of the following statements is correct regarding fuse wire?

It has a low melting point and high conductivity.

The correct answer is option 3. It has a low melting point and high conductivity.

The correct statement regarding fuse wire is it has a low melting point and high conductivity.

Fuse wire is specifically designed to have a low melting point so that it can melt and break the circuit when an excessive current flows through it. This property helps protect electrical circuits from damage caused by overcurrents. Additionally, fuse wire needs to have high conductivity to efficiently conduct electricity when the circuit is operating normally. Therefore, the correct statement is that fuse wire has a low melting point and high conductivity.
