low specific heat
high melting point
high resistance
low melting point
Answer is Wrong!
Answer is Right!
The correct answer is D. low melting point.
A fuse wire is a safety device that is used to protect electrical circuits from overloading. It is a thin wire that is made of a metal with a low melting point. When there
is an overload in the circuit, the fuse wire melts and breaks the circuit, preventing damage to the electrical system.The other options are incorrect because:
- A metal with a high specific heat would absorb a lot of heat before melting, which would not be effective in protecting the circuit from overloading.
- A metal with a high melting point would not melt easily, which would not be effective in protecting the circuit from overloading.
- A metal with a high resistance would cause a lot of heat to be generated in the circuit, which could lead to an overload.
