​Which of the following statements are correct?
(i) Tin-lead alloy is used for making fuse wires.
(ii) Fuse is connected to live wire.
(iii) The material chosen for making fuse should have high melting point.​

Correct option is B

The correct answer is option (b) Both (i) and (ii)

1. Tin-lead alloy is used for making fuse wires: Tin-lead alloys (commonly a mixture of 63% tin and 37% lead) are often used to make fuse wires because they have a low melting point. When the current exceeds a certain limit, the fuse wire melts and breaks the circuit, protecting the electrical system.
2.  Fuse is connected to the live wire: The fuse is typically connected in series with the live (or phase) wire in an electrical circuit. This ensures that if there is a fault or overload in the live wire, the fuse will blow and disconnect the circuit, preventing damage.
3.  The material chosen for making fuse should have a high melting point: The material used in a fuse needs to have a low melting point so that it can melt and break the circuit when the current exceeds a safe level. A high melting point would prevent the fuse from blowing in the case of an overload.
