Question

Name the material used for:

Electric fuse

Answer 1

1. Electric fuse is a safety device designed to melt and separate into two pieces and break a circuit in the event of overcurrent.
2. It operates to provide overcurrent protection of an electrical circuit.
3. It should have a low melting point.
4. It should have high resistivity.
5. Alloy of Tin$\left(Sn\right)$ and lead$\left(Pb\right)$ has the property of low melting point and low resistivity.

Therefore the material used for the electric fuse must be an Alloy of Tin$\left(Sn\right)$ and lead$\left(Pb\right)$.
