two bulbs of 100w and 40w respectively connected in paralel
across a 230v supply.which bulb will glow bright and why?

Obviously 100W bulb will glow brighter because voltage
across both bulbs are same but current flowing through 100W
bulb will be more compared to 40W and power of 100W bulb
will b more.
