Current Electricity Charging Discharging Of Capacitors Question 455
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
[CPMT 1990]
Options:
A) Zero
B) Greater than that of the fan
C) Less than that of the fan
D) Equal to that of the fan
Show Answer
Answer:
Correct Answer: C
Solution:
For constant voltage, we know that $ P\propto \frac{1}{R} $ So higher the power, lower will be the resistance.
