उत्तर
The fuse wire is made of a/an tin-lead alloy.
Explanation:
A fuse wire is commonly made of a tin-lead alloy because it has a low melting point and relatively high resistivity. When excessive current flows through the circuit, the fuse wire heats up and melts, breaking the circuit and protecting electrical appliances.
