A fuse wire is connected in parallel with the appliance it protects. 2. The material of a fuse wire has a low melting point.

Single correct option

Consider the following statements:
1. A fuse wire is connected in parallel with the appliance it protects.
2. The material of a fuse wire has a low melting point.
Which of the statements given above is/are correct?
  1. A. 1 only
  2. B. 2 only
  3. C. Both 1 and 2
  4. D. Neither 1 nor 2
Show answer and solution

Answer: (B) 2 only

A fuse must carry the full current of the appliance, so it is connected in series, and statement 1 is wrong. It is made from an alloy of tin and lead that has low melting point so that it melts quickly when the current is excessive; statement 2 is correct.
