Question

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

• A. Zero
• B. Greater than that of the fan
• C. Less than that of the fan
• D. Equal to that of the fan

Answer 1

Answer: (C)

Less than that of the fan

Answer 2

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