Solution: Schematic diagram showing common domestic circuits

The Importance of the Fuse

A fuse is a type of safety device that is used in both household wiring and electrical appliance design.
The fuse protects the circuit and the appliance from any damage that could occur as a result of an overload.
A fuse protects against an accidental fire that could occur as a result of a short circuit.
A specific rating of fuse is used in conjunction with a specific appliance. When a fuse has a lower rating, it will cause a great deal of inconvenience because the fuse will need to be changed on a regular basis. A fuse with a higher rating would be ineffective because it will not melt even if the current exceeds the device’s current rating limit. As a result, a fuse that has burned out should be replaced with another fuse of the same rating.
