• # question_answer An electric fan and a heater are marked as 100 watt, 220 volt and 1000 watt, 220 volt respectively. The resistance of the heater is                                                                    [CPMT 1990] A)            Zero B)            Greater than that of the fan C)            Less than that of the fan D)            Equal to that of the fan

For constant voltage, we know that $P\propto \frac{1}{R}$            So higher the power, lower will be the resistance.
