WHAT ARE THEY?- A thin metal wire
WHAT DO THEY DO?- The wire melts if the current is too high, breaking the circuit so no more current can flow through the appliance
WHAT IS THE POINT OF THEM?- Fuses prevent appliances from being damaged by surges in electricity, they warn owners of faults and help prevent fires
The correct fuse for an appliances is the one wth the current rating closest to and above the working current of the appliance..
e.g. an appliance wth a current (A) of 10.9 wll need a fuse wth a current rating of 13A
