Answer / pradeep kumar

100 watts would glow
brighter..! Because both the
bulbs were connected in
series..
So current flowing through
both would be equal..
Power output(brightness)=
I^2*R..
The bulb with high power
rating has less resistance..
So 100watts bulb has high
resistance.. So 100 watts
bulb's power output would
be higher..!!
