Question

An electrician is carrying out repairs in your house. He wants to replace a fuse with a piece of wire. ​​Would you agree? Explain.​​

Answer 1

• The material of the fuse wire should have a low melting point.
• So clearly, the electrician should not be allowed to replace the fuse in the house with a piece of wire. This is because every wire cannot be used as a fuse wire. A fuse wire must have a low melting point such that it could melt and break in response to a large amount of current.
• A fuse wire is specifically made up of an alloy of tin and lead. This material has a low melting point, which makes it apt to be used in a fuse wire.
• Usually the wires at our homes are made up of copper, which has a comparatively high melting point.
