Question

explain why fuse wire is made of a tin-lead alloy and not copper

Answer 1

HEY FRIEND !

Fuse is made of thin lead alloy and not copper because of the following reasons

1)This wire is consist of low melting point as well as the have the high resistance.

2) The alloy result in good functioning of the fuse. As the tin cause the good conductivity property . Also the low melting point occur due to the lead

3) Other wise the fuse can cause problem due to the surface corrosion...


#Hope this helps.

Answer 2

fuse wire is made up of an alloy of tin and lead ( called solder ) because it has a very low melting point so if a short circuit happens, the wire will melt and this will break the circuit. Copper can stand high temperature so it is not suitable to be used in fuses.
