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 / osho katyal

In domestic lines,we got parallel connections. So formula
P=V2/R is applicable .As such P and R are inversely related.
So power less more resistance less cureent.
