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=220vCurrent =1000/220=4.55AThe suitable fuse is 5A since it is slightly above the current flowing through the circuit.
