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. [3 marks]

Answer 1

• 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. [2 marks]
• 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. [1 mark]
