Dear Student Rating of the heater 110V-550Wthat means Voltage V=110 VPower P=550 WLet P=VII=PV=550110=5 AIf adding with the supply voltage V=220 VP=I2RR=PI2=5505×5=22 OhmPower consumedP=VI=220×5P=1100 W Regards

No links please A 110V-550W heater is to be used with a 220V mains. What is the minimum value of resistance that should be added in series with the heater? Find out the power of the whole circuit in that situation. [22 n,
