20.66 watts
Explanation:
Given load is lamp load. We know that lamp load is resistive in nature.
Since it is resistive in nature,hence it is our first duty to find out how much resistance it has.
power=voltage
Given bulb ratings are 100W&220volts.
If we substitute the ratings in
then we get resistance value.
Power consumed if 100v applied to 484ohm:
As given in the question , apply 100volts to 484ohm resistor .
