Q1: What is the purpose of a fuse and where would you use it?

[Answer]

A fuse is an emergency switch. It is a thin wire which will easily melt and break the flow of electricity when a circuit becomes overloaded.

A fuse is a vital piece of a circuit because, if wires or appliances get overloaded and heat up they can start fires.

Every home, and every appliance attached to the mains, must have a fuse of the correct value.
