Current in series connection is always same and voltage is
divided.here,
resistance of 40W bulb is higher than 100W bulb.
resistance of 40 watt is high so less current required to
glow a 40W bulb.
resistance of 100 watt is low so high current required to
glow a 100W bulb.
high resistance so voltage require more for glows = 40watt
glows more
similarly ,low resistance so voltage require less for glows
= 100w glows dim
formula I=V\R.
