Solution

Melting of Fuse wire in a short circuit appliance gets earthed:
The current from the metal body of the appliance flows into the earth if the appliance is earthed.
Then, there will be an increase in magnitude It rises in of current and in turn overloads the circuit.
As a result of this overloading or high voltage, the fuse melts.
