Question

Why is lead-tin alloy used for making fuse ?

Answer 1

Answer:

Fuse wire is made of a tin-lead alloy and not copper because of the following reasons: 1. They have high resistance due to high resistance the wire heats up quickly, when large current flows. ... They have low melting point which melts and breaks off the circuit if the current is larger than the safety limit.
