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 / joydeep kr. chakraborty
The Joule's formula P=I^2R holds good only if I through
them is Constant. But, when connected accross same voltage,
the current through a 40W bulb is less than a 100W bulb.
Thus, I^2R for 40W bulb will be much much less than that of
a 100W bulb.
If we connect them in SERIES and apply voltage to the
combination, the current passing through them will be same,
and in that case, the 40W bulb will definitely CONSUME MORE
POWER THAN 100W BULB.
