Answer 2

Here is ur answer....

Fuse : The function of a fuse is usually to prevent fire - that's the basic protection a fuse offers - between power supply and appliance there may be a few feet or metres of cable - if a short circuit occurs in the appliance, the cable could easily become overheated (due to excess current) and burn or rupture its insulation.

Earth wire : The earth wire creates a safe route for the current to flow through if the live wire touches the casing. You would get an electric shock if the live wire inside an appliance, such as a cooker, came loose and touched the metal casing.
