Question

An electric fan and a heater are marked as 100 watt-220 volt and 1000 watt-220 volt respectively. The resistance of 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

R_fan = $\frac{(220)^{2}}{100}$ , R_heater = $\frac{(220)^{2}}{1000}$

\ R_fan > R_heater
