Complete the sentence:
The fuse wire is made of low melting point material because
- When excessive current or heat is generated due to high voltage in the circuit, the fuse should melt down.
- When a large amount of current or heat is produced due to high current flow in the circuit, the fuse may melt down.
- When excessive voltage is generated due to heavy current flow in the circuit, the fuse should melt down.
- When the energy is generated due to heavy current flows in the circuit, the fuse should melt down.
Hint:
When a large amount of current or heat is produced due to high current flow in the circuit, the fuse may melt down.
The correct answer is: When a large amount of current or heat is produced due to high current flow in the circuit, the fuse may melt down.
- When a large amount of current or heat is produced due to high current flow in the circuit, the fuse may melt down.
- A fuse wire has a low melting point and high resistance.
