For us to get the fuse that is suitable, we must get the total current flowing through the circuit.

The formulae to get this is :

Power(watts) =Voltage(volts) ×current(amps)

In this case power=1000watts, votage=220v

Current =1000/220=4.55A

The suitable fuse is 5A since it is slightly above the current flowing through the circuit.
