Correct Answer: high resistance and low melting point.
Solution : The Correct Answer is- high resistance and low melting point.
It is an electrical safety device created to guard against overcurrent damage to an electrical circuit. Since there is a lot of current flowing through the fuse wire, the resistance must be high in order to prevent the fuse wire from overheating and breaking down right away. As a result, fuse wire has a low melting point and high resistance. A small, quickly ignitable wire called an electric fuse is inserted into an electrical circuit for protection.
