Explanation:
Introduction:
A fuse wire is a safety device that is used to protect electrical circuits from overcurrent. It is a thin wire that is designed to melt and break the circuit when excessive current flows through it. The choice of material for the fuse wire is crucial to ensure its proper functioning.
Conductivity:
The fuse wire must be conducting in order to allow the flow of electric current through it. This is important because the purpose of the fuse wire is to carry the current and protect the circuit. If the fuse wire were an insulator, it would not be able to carry the current and would fail in its function.
Melting Point:
The fuse wire must have a low melting point. This is because the fuse wire is designed to melt and break the circuit when excessive current flows through it. If the melting point is too high, the fuse wire may not melt quickly enough to break the circuit, leading to damage or failure of the electrical equipment.
Reasoning:
- Option A: Conducting and of low melting point - This is the correct answer. A conducting fuse wire with a low melting point ensures that it can carry the current and melt quickly when the current exceeds a safe level.
- Option B: Conducting and of high melting point - This is incorrect. A fuse wire with a high melting point would not be able to melt quickly enough to break the circuit and protect the electrical equipment.
- Option C: Insulator and of high melting point - This is incorrect. An insulating fuse wire would not be able to carry the current and would fail in its function.
- Option D: Insulator and of low melting point - This is incorrect. An insulating fuse wire would not be able to carry the current and would fail in its function.
Conclusion:
In conclusion, a fuse wire must be conducting and have a low melting point. This combination ensures that the fuse wire can carry the current and melt quickly enough to break the circuit when the current exceeds a safe level.
