Question

The electric wire used in the fuse has the characteristic features of:

  1. Low resistance/High melting point
  2. Low resistance/Low melting point
  3. High resistance/Low melting point
  4. High resistance/High melting point

Answer:

Option C: High resistance/Low melting point

Detailed Solution:

The correct answer is “High resistance/Low melting point”.

The electric wire used in a fuse has the characteristic features of high resistance and low melting point. This allows the fuse to melt and break the circuit when excessive current flows through it, thereby protecting the circuit from damage.
