what might happen if fuse is not there in household electric circuit

The question is ambiguously written, so let’s look at the two possibilities of what it might be asking:
If there is a fusholder, but no fuse within it, then the circuit is incomplete and no current will flow. The circuit is ‘dead’If the circuit has been built without a fuseholder, then it will be live and will work normally but without any protection from an overload or a defect. If a short circuit occurs, then current will continue to flow until the upstream protection kicks in (the “company fuse” in a household supply is typically around 50 to 100 times bigger than a circuit fuse).
In the second case, the fault current flowing in the defective circuit will cause heating and potentially cause a fire before the upstream protection opens the circuit.

If fuse is not here in the circuit,then by any chance if the current passes through the circuit larger than the required value,it can cause severe damage to the appliances and can get the house on fire.
