The correct Answer is:

The common material used as furse wire is an alloy of tin and lead (63% tin and 37% lead). Fuse wires provide overcurrent protection of an electrical circuit including the source of power and the load. Its essential component is a metal wire of strip that melts when too much current flows through it, thereby interrupting the flow of current.

Assertion (A): Fuse wire is made up of an alloy constituted oflead and tin in 1 : 1 ratio by mass. Reason (R): Both lead and tin have comparatively low melting points than other metals.

Both (A) and (R) are true and (R) is the correct reason of (A).

Both (A) and (R) are true but (R) is not the correct explanation of (A).

(A) is true but (R) is false.
