if 40 watt bulb has higher resistance then a 100watt bulb
then according to joul farmula p=I^2R the 40 watt bulb more
power consume then 100 watt bulb.
Answer Posted / kiran
even if u take the resistance of 40 watt bulb higher than
100 watt bulb,as the current varies square(I^2) the power
consumption,so power consumed by 100 watt is higher than
former........
